Leafy Cobweb Spider
There are over 600 known species Worldwide within the Theridion genus, making them one of the largest groups of spiders. This particular species is found from Southern Canada, southward to Alabama and west to North Dakota.
Females make an egg sac in late spring that hatches sometime in early August. She will place the egg sac within a curled leaf and guard it. Once the spiderlings hatch she will remain with them for a short period time. This maternal care helps protect her offspring from predation. After several molts the young spiders will spend the winter as sub-adults and emerge in the spring to finish their lifecycle into an adult spider.
These are truly one of the most beautiful little spiders I've ever encountered. If you would like to find one, try sifting through leaf litter on the ground and who knows what surprise creature may turn up.
