Monochamus males have some of the longest “horns” of any Cerambycids here in the northwest. These antennae are used to “smell” for females and are often more than twice their body length.

This tiny (5mm) leaf beetle is common in moist forests throughout the Pacific Northwest west of the Rockies. They seem to be particularly fond of hanging out in Hydrophyllum flowers.

These large (3 cm), circumboreal beetles get their name from the leathery odors they emit from their exoskeleton (Osmo- means smelly, derma means skin). Adults spend most of their lives feeding on the decaying centers of fallen logs.

I found these massive woodborers in abundance (even on campus here at the U of MT) for a few weeks between late June and early July. They’re especially easy to identify in flight. Just listen for the miniature helicopter.
