Violet Longhorn
A compact, flat cerambycid with a striking metallic violet coloration across its entire body. Widespread in conifer forests of the Northern Hemisphere, it breeds in dry dead conifer wood. Adults are occasionally found in houses after emerging from firewood.
Did You Know?
Larvae can survive in kiln-dried timber and have emerged from furniture and log cabin walls years after construction.
Painted Hickory Borer
A handsome cerambycid with white zigzag markings on dark brown elytra, breeding in dead hickory and oak in eastern North America. Adults appear in spring, unlike the autumn-active locust borer. It is frequently found on freshly cut firewood.
Did You Know?
This species and the locust borer are near-perfect lookalikes but are separated by season: spring vs. autumn emergence.
