Longhorned beetles, roundheaded woodboring beetles. About 24,000 species worldwide. Predominantly borers in trunks and branches of dead and dying woody plants. A few species attack living trees and are regarded as economic pests.

Amorpha borer on goldenrod

One of my favorite longhorned beetle species is the amorpha borer, Megacyllene decora. Like its close relative, the locust borer—M. robiniae, this large, beautiful, black and yellow beetle is a classic harbinger of fall by virtue of its late-season adult activity period and affinity … Continue reading

Black is beautiful!

Most species in the genus Crossidius exhibit varying amounts of yellow/red/orange coloration on the body.

A Crossidius hirtipes subspecies blend zone…
