They develop in dead or dying pine and spruce that have been burned or otherwise damaged, and females are drawn to the smell of burnt wood. The beetle needs three to four years to finish its life cycle, laying eggs in bark cracks soon after a fire; adults emerge in spring through autumn.

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.
