The Castianeira longipalpa spider is a member of the family of Corinnidae spiders. It is an ant-mimic spider found in North America, displaying activity similar to carpenter ants.
Size: Male: 1.3 cm Female: 0.3-0.6 cm
Color: They are a brownish-orange, with the abdomen covered in black stripes.
Other Characteristic Features: They mimic carpenter ants by “stroking” their front pair of legs like antennae and “nodding” their abdomen.
The egg sacs are white, flat discs attached to surfaces containing around 10 eggs.
After hatching, the spiderlings overwinter until the spring.
As active hunters, they do not produce a lot of webbing to trap prey.
Bites rarely occur as their fangs are not strong enough to pierce human skin.
| Lifespan | 1-3 years |
| Distribution | Canada and the United States |
| Habitat | Under rocks or stones and logs, or in leaf litter |
| Diet | Small insects like ants |
