The speckled wood has a wingspan of about 5 cm, with males a bit smaller than females. It lives in many grassy and flowery spots in forests, meadows, urban parks and gardens. Adults feed on various grasses and the species can overwinter as either a pupa or a half-grown larva, leading to several flight periods each year.

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.
