Partridge Pea, Beneficial to Bees and Butterflies Alike

 Partridge Pea, also referred to as the sleeping plant, is a common legume (member of the bean family) in Missouri and much of the eastern United States. It is found in a wide variety of habitats, including savanna, glades, and along riverbanks but also does well in poor soil such as road banks, ditches, abandoned fields and heavily grazed pastures. 

Occasionally partridge pea is purposely planted to aid in road bank erosion, as it grows rapidly and spreads profusely. This plant is insect pollinated by long tongued bees, such as minor bees, bumble bees, honeybees, and large leaf-cutting bees. Honeybees often rely on this plant in areas where appropriate nectar plants are scarce. The nectar flow of this plant is not produced in, or reached by means of the yellow flower, but instead, is accessed through an orange gland at the base of the leaves. In many areas this plant is planted in recognition of their important nectar content. Sometimes leaf-cutter bees will portion off parts of the petals to provision their brood nest with. Three Sulphur butterflies use this plant for their host. You will likely find Little Sulphur, Sleepy Orange and Cloudless Sulphur caterpillars feasting on the foliage.

Bobwhite quail, greater prairie chickens, pheasants and other grassland birds feed on the seed of this plant, the seeds are viable throughout the winter, so therefore they are an important part of these birds’ diet. Because of this plants tendency to grow in thick clumps, young birds, not yet experienced with the risk of predators utilize the thick foliage of this plant as means to hide and camouflage themselves.

Partridge Pea begins blooming in mid to late summer and blooms until the first frost. With sufficient moisture it will retain flowers throughout this entire time. The blooms are somewhat sensitive and will partially close when touched or disturbed. If you raise cattle, be careful, this plant is toxic to cattle. The plant contains a cathartic substance that when consumed in substantial quantities can be stressful to cows and has the potential to ultimately cause death. They like the flavor of this plant, and they will readily consume it. It would be best to not grow this plant near livestock. Although classified as an annual, this plant readily reseeds itself. In areas where this plant is readily pollinated it will produce large amounts of seeds. These seeds are consumed by birds and later dropped in their waste in areas where cows feed. In certain areas ranchers and livestock growers will have to be vigilant and remove plants. In other agricultural settings, away from cattle, this plant has the benefit of adding nitrogen to the soil and makes an excellent cover crop. This plant is also known to attract natural predators of the insects and pests you do not want feeding on your crop. Therefore planting, or encouraging the natural spread of partridge pea around the edges of crop fields goes a long way toward natural insect pest control

 

Many Native American tribes recognized the benefit of this species of plant and used it in natural healing, the Seminoles used it to treat nausea. It was also used as a laxative but considering the plants toxic properties I would imagine the treatment was worse than the ailment! The Cherokee used it as a stimulant to ward off fainting spells as well as to keep sports players from tiring out. Those of us who like to "grow native" utilize this beautiful plant within our gardens. It is easy to grow, has beautiful yellow flowers and showy feathery leaves. It loves full sun and is drought tolerant which we know is hugely important in Missouri, when we have no idea if the summer rains will come or not. This plant readily attracts bees, butterflies, and birds, which is a bonus to us nature lovers.

Grass Spider

 Nothing says summer like the endless string of webs left by the grass spider.

As summer reaches its end, days are beginning to get shorter, temperatures are more favorable, and we begin noticing large webs all over our yards. These webs, often glistening with dew in the mornings, are made by one of the most common spiders found throughout North America, the grass spider. The sparkling of the dew-covered webs is truly beautiful, and turns each web into a work of art. There are nearly 1200 known species Worldwide within this family and nearly 120 of them call North America home.

Their sheet-like web spreads out for a foot (or more) in a circular fashion with a distinct funnel-like opening near the center. It is this opening that earned them another common name of funnel web spider. These spiders should not be confused with another spider that goes by a similar name which is the Sydney Funnel Web spider of Australia.

The grass spiders belong to the Araneomorph spiders which are true spiders or modern spiders, whereas the Sydney Funnel Web spider belongs to a family of old-world spiders similar to tarantulas and trapdoor spiders called the Mygalomorph. The Sydney Funnel Web spider has earned a nasty reputation as being one of the deadliest spiders in the world. You will not find these spiders in the United States! Grass spiders are harmless, and not likely to bite unless mishandled. These shy spiders would rather avoid humans and are quick to retreat into their webs. Their fangs are small and not strong enough to puncture skin, except for the elderly and infants. Bites are not known to be serious but should be cleaned to avoid infection should one occur. These spiders will on occasion come into your home, but these indoor visits are rare unlike other species that are more prone to do so.

Grass spiders are medium-sized spiders with a legspan up to 1 1/2 inches. Their color varies from pale yellowish tan with gray markings to reddish-brown with black markings. Their abdomen is gray to black along the margins with a light brown to brownish-red stripe bordered by lighter colored spots. They have very long legs that are banded at the joints. These legs are usually held out in front of the spider at the opening of the funnel.

The females rarely leave the security of their web except to find a new location to build a web. They hide out at the opening of the funnel lying in wait for an unsuspecting insect to crawl across the web. They will run rapidly out of their hiding place and envenomate their quarry and drag it into the funnel to consume at their leisure. The webbing of this genus is not sticky like other spider webs, they instead rely on capturing their prey by using their extremely fast acting venom. 


Males are wanderers and are constantly on the look-out for food and for mates. When a male comes upon a female of his own species he will approach cautiously, after all he does not want to become her next meal. After determining the female is receptive of his attention, he quickly dominates her. By no means is he out of danger, he must make a hasty retreat before she changes her mind and decides he looks scrumptious. Males die shortly after mating, leaving the females to deposit an egg sac under the loose bark of a tree that she will guard until the first frost. Once the first frost comes the female will die often still clinging to the egg sac, making the ultimate sacrifice. Her life for the life of her offspring. Some species of funnel web spiders may live up to two years, but most only live one season.

Many people find their webs unsightly spread across a normally well-manicured lawn and would prefer they weren’t there. Because of the nature of the low-lying web and its tendency to collect debris like leaves and small twigs these webs can begin to look rather unkempt. So how do you get rid of them? There are several things a person can do to help control the number of webs you are dealing with. Make sure any food crumbs, or other sources of human food are picked up. Do not leave pet food out all the time. Mow your lawn more frequently, and trim back bushes, and overgrown vegetation. Eliminate brush piles and using an old broom to remove the webs. By cleaning up the environment the spiders are building the webs in, you are discouraging the prey insects they feed on. If there is no food readily available, the spiders will be encouraged to build somewhere else where there are more resources. Or if you are like me, appreciate the webs for the works of art they are, and rest assured they are helping control insect populations and providing free pest control.
