Cheiracanthium mildei
Cheiracanthium mildei is a species of spider from the family Cheiracanthiidae. "C. mildei" is commonly known as the northern yellow sac spider, a name it partially shares with many other spiders of its genus. Description. "C. mildei" usually has a pale green or tan body, with darker brown palpi and chelicerae. An adult "C. mildei" is usually in body size. Each leg ends in double claws, and the front pair is significantly longer (up to two times the size, however it is clearly shorter than in "C. inclusum" species). The eyes have a tapetum lucidum that reflects back  to the light source once lit, suggesting that the spiders have good to excellent vision and are agile prey hunters. Although this spider can bite humans, the effects appear to be mild. Habitat and distribution. "C. mildei" is native to Europe and North Africa through 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. Prey and predators. "C. mildei" is  a dominant predator of "S. littoralis" (a moth species) in Africa and Mid Eastern regions. The mechanism of predation include causing direct death by consuming the larvae and causing indirect death by dispersing larvae from its host plants.
