The northern yellow sac spider is a member of the family of cheiracanthiidae spiders. It shares its name with several other members of its genus.
Size: 0.7–1 cm
Color: This spider is pale green or tan, with dark brown mouthparts and palpi.
Other Characteristic Features: Their eyes have a layer called the tapetum lucidum, which reflects light to the source from where it was emitted. This indicates that they have excellent vision.
Cheiracanthium mildei
Females produce 4-7 egg sacs over a single mating period, with the total number of eggs ranging from 240 to 1900.
The young spiderlings will leave the safety of their silk sac at night to hunt while returning in the day.
As they are primarily hunters, they do not produce a lot of webbing.
This spider’s venom is not deadly to humans, and their bite is not very painful.
