Broad-Faced Sac Spider

September 22, 2019

Trachelas tranquillus




The Broad-Faced Sac spider produces a painful, albeit reportedly non-lethal bite. Their bite can cause secondary infections, believed to be from the spider’s diet of dead arthropods. They are found across the midwestern United States and Canada.

Females typically lay 30 to 50 eggs in a white egg sac around September or October.
