The Corinnidae family consists of some small to medium running spiders. Some of the species are known for imitating ants to survive. The family has around 872 species under 68 genera.
Size: Members of this family are medium-sized.
Color: Most species are black, with brown and white tips on legs and abdomens. However, the coloration differs from one species to another.
Other Characteristic Features: They have anterior spinnerets with a conical shape.
Not much is researched about the eggs of the spiders of this family. But, a few species, like red-spotted ant mimic spiders, some produce silk sac for storing their eggs in. Eggs are possibly cream-colored and oval in shape.
Spiderlings hatch after a certain point and some species of the family go through molten phases before becoming adults.
They might not make webs for catching preys, but some species of Corinnidae family, build webs to live near the ant colonies.
Not all species are well evaluated, but it can be said that their bite is not harmful to humans. Although the bite might result in pain and allergy, something serious is unlikely to happen because of it.
