Northern yellow sac spider

Appearance

"C. mildei" usually has a pale green or tan body, with darker brown palpi and chelicerae. An adult "C. mildei" is usually 7–10 millimetres in body size. Each leg ends in double claws, and the front pair is significantly longer. The eyes have a tapetum lucidum that reflects back to the light source once lit, however the "canoe-shaped" tapetum they possess is incapable of forming sharp images, so the benefit of these tapetum is uncertain, although they may assist in navigation through the detection of the polarization of light from the sky. Although this spider can bite humans, the effects appear to be mild.

Distribution

"C. mildei" is native to Europe and North Africa through the Caucasus to Central Asia. It is introduced to the United States and parts of South America. It widespread across the northeastern United States and eastern Canada, and can be found outside, or more commonly inside houses. It is thought to have been introduced into America from Europe by English colonists.
