Cheiracanthium mildei
Northern Yellow Sac Spider, Long-legged Sac Spider
Cheiracanthium mildei is a medium-sized spider native to Europe and North Africa, introduced to North America and parts of South America. Adults measure 7–10 mm in body length with pale green or tan coloration, darker palpi and chelicerae, and characteristically long front legs up to twice the length of others. It constructs silken retreats rather than capture webs, hunting actively at night. The species is frequently encountered in human dwellings, particularly in northern regions of its introduced range, and has been documented to bite humans with generally mild effects.
