Bug Hunting attracts Police

Last Thursday while we were in Townsend, TN I wasn't having much luck finding insects around the cabin where we were staying, so I asked my husband if he would drive me to the main street in town and look by the businesses with lights. He said he would, so we headed that way. The first likely looking place was a car wash, it had a lot of bright lights around it, we turned into the drive and a police car pulled in behind us. So I told Joey to pretend we were going to vacuum out the van. As soon as we pulled up next to the vacuums the police car did a u-turn and left. We found several really nice insects at the lights, including HUGE Eastern Sawyer Longhorn Beetles, one Eastern Dobsonfly, and an Io Moth. I was so excited I told him we needed to go to another location. We drove down the road to a place called the Heritage Center, we no more and pulled up and shut the van off when a pickup complete with flashing red and blue lights pulled in behind us. I just looked at Joey and smiled. I walked back to the officer, he was on his radio talking to dispatch about our van. When he was done talking he just looked at me and said "Is everything alright?" I just smiled and said "yes sir, everything is fine". I said "I'll tell you why we are here if you promise not to laugh". He said "ok". So I explained that I was bug hunting. He gave me the strangest look, and I certainly can't imagine why. He replied by telling me we weren't breaking any laws. LOL imagine my relief. He left, and I looked over to Joey who was trying real hard to find a rock big enough to hide under....LOL He just said "That was embarrassing". I found the whole thing very humorous.
We returned home Saturday evening from our vacation, and last night was a balmy evening with storms brewing in the area and I thought it would be a good night to hunt bugs. Joey said he would come outside with me and hold the flashlight, he emerged from the house in his Tighty-whitey's and work boots. Boy was he attractive...what a turn-on...or off!
It was so funny though, I teased him and asked him what he would do if someone pulled in the driveway? He laughed and said no one better. We looked around outside for about 20 minutes, and he was ready to go back inside. So I told him I would be in after a bit that I wanted to check one more spot near the highway. He went inside, and I was shining my flashlight around in the trees, when a car pulled in the driveway, and a man got out. Next thing I know I had a spotlight beaming off my eyeballs blinding me. I knew it was a deputy. I hear him say "Oh, it's you" I was thinking Well who else did you expect. I just smiled and he asked me what I was doing, I replied by telling him I was bug hunting and taking pictures. He got the strangest look on his face, I'm sure he thought I was certifiable! He said he got concerned when he saw lights flashing off the trees at 10:30 at night. Fortunately I knew him, he went to school with Joey and was very helpful to us when our son had a bad wreck last October. So...I told him he should have pulled in 5 minutes sooner and he would have seen Joey in his skivvies and hiking boots. He replied "That's what is nice about living in the country" We laughed a little and he left. I couldn't wait to get in the house and tell Joey and our son Joel. I retold the whole story including telling the deputy about Joey's outfit of choice. Joel started laughing as the mental image hit him of his dad outside in nothing but underwear and hiking boots and that deputy shining his spotlight on him. Then it started me to laughing, and I laughed until my sides hurt. Oh how I wish he would have gotten caught with his pants down! So I've come to the conclusion that hunting bugs may end up getting me arrested, and Joey charged with indecent exposure!

1st Tennessee Arthropod--Red-Sided Flat Millipede

This beauty is the Leach's Millipede (Sigmoria latior). While staying in Townsend, TN I was hoping to find numerous insects, and while I didn't find huge numbers of insects or other arthropods; the ones that I did find were interesting. This gorgeous millipede was crawling across the deck of the cabin we were staying at. I had just reluctantly left the comfort of the hot tub, when I noticed this thing crawling quite rapidly across the porch. At first glance I thought it was a caterpillar, imagine my surprise to discover what it really was. I was little concerned about handling it, as red is usually a warning coloration and I know that many millipedes exude a chemical secretion that can cause burning or skin discoloration. I do not know if this particular species has that ability, but I didn't want to take the chance. I captured him and plan to use him as an exhibit arthropod for our upcoming Insect-O-Rama event. This particular specimen was approximately 3 inches in length, and once again I am unsure if this is as big as they get or if bigger ones can be found. About the only information I could find on them states they prefer the rotting wood of hardwood trees. Associated with long leaf pine woods and oaks. They are common, but this was the only one I could find, and believe me I looked frequently around our cabin.This dark brownish-black millipede was laying on a walking trail near the Cades Cove area of the Smokey Mountains. A Harvestman was munching down on the unfortunate victim. The Harvestman (a.k.a Daddy Longlegs) were HUGE in this area. WAY bigger than anything we have in NWMO. I am unsure of the species of this Millipede, but I believe it is Narceus americanus. These are one of the biggest millipede, if not the biggest in the Eastern United States.

Green Bottle Blowfly



Green Bottle Blowflies belong to the genus of flies called Lucilia. They are large flies reaching lengths up to a 1/2 inch. They can be metallic blue-green or golden in color with black markings. There are black bristle-like hairs and three cross grooves (visible in the second picture) on the thorax. They have large reddish colored eyes. These flies are very common and can be found almost anywhere, city or country. The adults feed on sweet nectar, and picnic favorites, as well as garbage. They are very fond of sweet treats like pop. After mating, the females will lay eggs in masses of up to 20 eggs on the wounds of animals or on decomposing animal carcasses. Once the eggs hatch the pale yellow maggots will feed on the decaying animal matter on which they reside. It can take as few as two to as many as ten days to reach their full size. Once reaching full size they will fall to the ground and pupate. In a few days the adults will appear and begin the cycle all over again.


This species was raised for their offspring (maggots) for maggot therapy, this was done predominantly before the advent of antibiotics. Maggot therapy is still being used today in some extreme cases where wounds do not respond to antibiotics. Maggots prefer feeding on rotting and dead flesh, and leave living good flesh alone. So for bad wounds that refuse to heal, these maggots can be life saving, even if it does make ones stomach roil at the thought.

Ambush bug

Ambush Bugs in the genus Phymata are little predators measuring about 1/4 to 1/2 inch in length. They are found throughout the Eastern United States. Look for them in meadows, open fields, prairies, almost anywhere there are wildflowers. They seem to be especially abundant late in the summer and early fall when the goldenrod begins to bloom. Ambush bugs prey on insects in all stages of life. After mating, females will lay eggs in small clusters on the leaves and stems of plants. After hatching, the wingless nymphs will begin hunting for tiny insects to feed on. They will complete four molts (instars) before reaching adult size. Some species may take up to seven molts. The adults will overwinter in a secure place, probably among leaf litter or at the base of plants under vegetation. These bugs almost always hunt for their insect prey on flowers. They are able to fly but they rarely do so as they are weak fliers. Because of their coloring in shades of greens and browns they blend in well with their surroundings and are often overlooked. As you can see by the above picture they would be great at "ambushing" their prey. They are capable of sitting completely still, and will remain unmoving until a likely, delectable dining option comes along. They will then reach out with their longer front legs and grab the unsuspecting insect and pull the squirming little morsel into their mouth.

Bess Beetles


Today we made a trip to Tennessee for our family vacation. We are sitting at the Radisson Inn in Nashville, and plan to spend a few days here. We will probably visit the zoo, and the Grand Ole Opry. Tuesday we leave for Townsend, TN where we rented a cabin near the Smoky Mountains. I hope the insect activity at the cabin is good. I plan to take lots of pictures, and post some Tennessee Insects soon.

Tonight as the family watches some crazy comedy show on HBO, I decided to take the time to post about some very large beetles that I found in a hollow, rotting stump in our backyard. I literally tore that stump apart to see what was residing inside it. My husband said he wished he had the camera to get a picture of me. I apparently looked like a crazed woodpecker on crack as the wood flew in all directions in my quest to see what was residing in what was sure to prove to be the ultimate critter hotel. I was excited to find some very large beetles, called Bess Beetles.

This stump contained each life stage of this beetle.

1.) Bess Beetle Grub
2.) Bess Beetle Pupae
3.) Newly emerged Bess Beetle ( they are reddish in color when first hatched from the pupal cell, later turning black)
4.) Close-up of the face
5.) Fully matured adult

Bess Beetles (Odontotaenius disjunctus) are found from the Central United States and eastward. They go by many different common names including Peg Beetle, Betsy Beetle, Bess Bug, Patent Leather Beetle, and Horned Passalus. They grow quite large and with that horn on their face they can look very intimidating, but they are not known to bite. These beetles have a unique life cycle, the female will lay eggs within rotting stumps or other decaying wood. Both adults will care for the young larvae. They feed their offspring bits of chewed up wood. It takes up to one year for them to complete their life cycle to adulthood. It is not uncommon for the adults to consume injured larvae. Both adults and larva are capable of making squeaky noises through stridulation, by rubbing their abdomen against their wings. This is a form of communication between adults. If handled they will stridulate loudly. Look for them in or near deciduous woodland. Adults feed on decayed wood or fungus. Larvae feed on the chewed up bits of wood and fungus the adults give them. Both adults and larvae will also feed on their own fecal matter. This is done probably to insure they have the proper intestinal parasites that they need to digest cellulose from the wood fibers they consume. If you want to find these beetles look for a rotten stump or rotting logs and tear them apart, you are sure to find some as they are quite common. If not, well perhaps there will be something else even better.

Gnat Ogre

This super tiny robber fly in the genus Holcocephala is found throughout the eastern portion of the United States. There are three species within this genus and all of them are located East of the Rockies. Measuring 1/2 inch or less they are the smallest robber flies encountered in their range. The wide set eyes is a key characteristic of these flies and distinguishes them from any other robber flies. They are often referred to as Gnat Ogre's because of their diet, which consists almost entirely of gnats. Look for them in grassy open areas where they will perch on small stems or twigs waiting for dinner to pass by, and with the huge populations of gnats I'm sure they have no trouble whatsoever in finding plenty to eat. Start looking for them now during the mid summer months, when their numbers increase. Keep in mind their small diminutive size when searching for them, they would be easy to pass by without ever knowing they are there.

The Spider and the Fly

Mary Howitt wrote a poem about the Spider and the Fly that I have always loved. This picture reminded me of it so much I decided to share it will all the readers in case they had never heard it before. It really looks like this tiny spider bite off more than it could chew. The spider was smaller than one wing on that giant horse fly, but that didn't slow him up one bit. Before the fly knew what hit him, he had been bitten, paralyzed and wrapped in silk!


The Spider and the Fly
By: Mary Howitt

Will you walk into my parlor? said the Spider to the Fly.
Tis the prettiest little parlor that you ever did spy,
The way into my parlor is up a winding stair,
And I've many curious things to show when you are there.

Oh no, no said the little Fly, to ask me is in vain,
For whom goes up your winding stair, can ne'er come down again.

I'm sure you must be weary, dear, with soaring up so high
Will you rest upon my little bed? said the Spider to the Fly.
There are pretty curtains drawn around; the sheets are fine and thin,
And if you like to rest awhile, I'll snugly tuck you in!

On no, no, said the little Fly, for I've often heard it said
They never, never wake again, who sleep upon your bed!

Said the cunning Spider to the Fly, Dear friend what can I do,
To prove the warm affection I've always felt for you?
I have within my pantry, good store of all that's nice
I'm sure you're very welcome; will you please take a slice?

On no, no said the little Fly, kind sir, that cannot be,
I've heard what's in your pantry, and I do not wish to see!

Sweet creature! Said the Spider, you're witty and you're wise,
How handsome are your gauzy wings, how brilliant your eyes!
I've a little looking-glass upon my parlor shelf,
If you'll step in one moment, dear, you shall behold yourself.

I thank you, gentle sir, she said, for what you're pleased to say,
And bid you good morning now, I'll call another day.

The Spider turned himself round about, and went into his den,
For well he knew the silly Fly would come back again
So he wove a subtle web, in a little corner sly,
And set his table ready, to dine upon the Fly.

Then he came out to his door again, and merrily did sing,
Come hither, hither, pretty fly, with the pearl and silver wing,
Your robes are green and purple, there's a crest upon your head
Your eyes are like the diamond bright, but mine are dull as lead!

Alas, alas! how very soon this silly Fly,
Hearing his wily, flattering words, came slowly flitting by
With buzzing wings she hung aloft, the near and nearer drew,
thinking only of her brilliant eyes, and green and purple hue.

Thinking only of her crested head, poor foolish thing!
At last, up jumped the cunning spider, and fiercely held her fast.
He dragged her up his winding stair, into his dismal den,
Within his little parlor, but she ne'er came out again!

And now dear little children, who may this story read,
To idle, silly flattering words, I pray you ne'er heed.
Unto an evil counselor, close heart and ear and eye,
And take a lesson from this tale, of the Spider and the Fly.

Eastern Cicada Killer



Eastern Cicada Killers (Sphecius speciosus) are large wasps, reaching lengths up to 1 1/2 inches. They are very common east of the Rockies and are found at woodland edges, in gardens and waste ground. They are easily identified, their head and thorax are rusty colored, and their bodies are black and yellow banded. The wings are a clear amber color. Adults eat very little, but will take nectar occasionally from various flowers. After mating, the female begins looking for a suitable site to dig a burrow. She will then look for food to provision this lair. As their name implies they hunt cicadas. Once an unfortunate victim has been located she will sting the cicada to paralyze it, she then carries it with her massive legs to the burrow. Once entrenched in the burrow she will lay an egg on the very much alive but unmoving cicada. The egg will hatch in a few days and the newly born larvae will feed on the food provided by its mother. After consuming the cicada, and when nothing but a shell remains the larvae will pupate. It will remain in this restive state until the following spring, when it will emerge as a full grown adult and the cycle will repeat itself. These wasps usually become abundant in the mid summer months with the return of the cicadas. They are not known to be aggressive, as with most solitary wasps they have nothing to protect. Colony bees or wasps tend to be much more aggressive as they have a queen, hive and larvae to protect. If you were to swat or otherwise antagonize one of these wasps make no mistake it would defend itself, and a sting from one of these large wasps would be an experience you wouldn't soon forget. The one pictured here was drawn to a sedum and had been hanging around this same plant for over a week. It seemed like unusual behavior, especially since the plant wasn't blooming. It allowed me to approach it to within a foot and take pictures. Occassionally darting out to chase off other wasps. They are beautiful, intimidating looking insects with a fascinating life cycle.

Arabesque Orb Weaver


This gorgeous spider is the Arabesque Orb Weaver (Neoscona arabesca), they are one of the most common orb weavers in North America. They can be found in a wide variety of habitats, but tend to prefer woodlands. It is not uncommon to encounter several of these spiders all within just a few feet of each other. These spiders are very efficient at insect control, with such large populations of them it stands to reason that they consume untold amounts of insects. While they aren't as flashy as some orb weavers such as the Black and Yellow Garden Spiders, they are certainly pretty in their own right. With golden coloring and bright white and golden abdomen they certainly stand out. One distinguishing characteristic of this species is the dark brown comma shapes on their abdomen, which are visible in the second and third picture. Each day they consume their web and build a new one. Silk is a valuable commodity and none goes to waste. Building a new web insures that the silk is strong enough to hold any insects that become ensnared within
it. I have tons of these spiders in my
yard and have to dodge the webs, as they tend to build wherever the mood strikes them. I cannot tell you how many time I've walked directly into their web, this freaks me completely out. I've invented some pretty unique dance moves, as I try to detangle myself from these sticky webs. Then I imagine the spider on me somewhere, which starts the fancy footwork all over again. EWWWW! I like them just fine in their web munching away on insects, but when they invade my space....GAME ON!

This one is for Caleb---YellowJackets mistaken identity

(Yellow-Jacket Queen)

When I heard about young Caleb's unfortunate encounter with a nest of yellow-jackets I couldn't help but feel sympathy for his experience. His father said he had over a dozen stings and now is very uncomfortable being near any bees, especially the ones near their bird feeders. I can certainly understand how anyone would feel this way after having such a bad experience. His father asked me if I would post an entry about Yellow-Jackets and I am very happy to do so. Caleb my hope is that after you read this you will have a little better understanding as to why those wasps were so angry with you and what prompted them to sting so viciously.
Eastern yellow-jackets belong to a family of wasps called Vespidae, also within this family are the paper wasps. Like paper wasps, yellow-jackets build a papery nest out of chewed up bits of wood and saliva. These nests are most generally found underground, but can also be found in hollow trees or even in hay piles as the one pictured here. In the spring, bred females become active as soon as the weather begins to warm. She will seek a suitable nesting site and begin construction of her new home. She will lay eggs in small chambers (cells) within the nest and feed these young chewed up bits of insects herself. Once these young have grown to adulthood, they will take over the care of the queens offspring, and the queens sole purpose will be to lay eggs. These new wasps are referred to as the workers and their job is to not only care for all their siblings, but to expand the nest and to defend it. It was this defensive nature that Caleb learned about up close and personal. Yellow-Jackets give off a pheromone (chemical perfume) that alerts other members of the hive when danger is near. When one yellow-jacket is alerted, it isn't long before many are also on the defensive. If you happen to wonder too close to their hive they perceive this as a threat and attack accordingly. They are estimated to be responsible for over half of all stings from any wasp or bee. Although it is truly nothing personal, they are doing what nature designed them to do, defend their queen, their siblings and their home. Much like a father would do, if someone threatened his family or home. While he may not possess a stinger on his rear end, he certainly would use whatever was at his disposal if he thought there was a threat to his family or home. (Yellow-Jacket female foraging)

Each hive can contain up to 5,000 members, which sounds like a lot, but really that is a small hive when you consider that honey bees will have up to 50,000-60,000 members.
Late in the summer the male yellow-jackets appear on the scene and begin looking for young females with which to mate. After mating, and when cold weather begins to set in all in the hive will perish except for the bred females. These females are destined to be next years queens. They will spend the winter months in hiding, under leaf litter or in hollow trees.
(Yellow-Jacket Hive)

Fortunately for us Yellow-Jackets aren't always so aggressive, usually while out foraging for food they are docile. If provoked they will defend themselves, and can sting repeatedly. They are attracted to sweet substances and are often encountered at ball games, picnics, etc., where pop and other sweet drinks are plentiful. They are commonly seen crawling all over pop cans or edges of cups sipping up the sugary treats. Because of their resemblance to honey bees, many people mistakenly refer to them as honey bees. It would be very unlikely to encounter a honey bee on your pop can, they instead prefer flower nectar and pollen. Honey bees often get a bad rap because of the yellow-jackets. One thing to remember is: Yellow-Jackets are wasps, Honey Bees are bees. Honey bees can only sting once then they die, not so with yellow-jackets. Honey bees have fur, whereas yellow-jackets are smooth. Honey bees are milder in temperament and aren't as easily provoked. Yellow-jackets are more easily irritated. Another bee that is often mistaken for yellow-jackets is the cuckoo bee, they mimic yellow-jackets so closely it would be very hard to tell the difference. I assume this extreme mimicry offers them protection, after all if you look like a big bad mean wasp, not much will mess with you.

(Cuckoo Bee) (Honey Bee)




















Caleb, I hope this helps you better understand these little wasps. Try to not be afraid, the ones that are at your bird feeders are most likely not going to cause you any harm. They are merely looking for something to feed either themselves or their younger siblings. Getting too close to the nest is never a good thing as you found out, but I hope you don't let it discourage you from respecting these amazing insects. While they do tend to be aggressive by nature, they are beneficial in respect to all the insect pests they kill and use to feed their offspring.
