The drumming sword wolf spider is a wolf spider that lives in beech-maple forests of the United States and Canada, where it occupies ground, herb and shrub layers. It is nocturnal, hiding by day, and the female carries her eggs in a spherical sac; after hatching, the spiderlings may ride on the mother until they can fend for themselves.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
