The locust borer beetle is native to North America. It attacks only black locust trees of the genus Robinia, which originally grew only in the Allegheny and Ozark mountain regions. Locust borer larvae tunnel into a tree’s trunk and branches, weakening the tree and making it susceptible to wind breakage. The brightly colored adults appear when goldenrod is in bloom, generally mid-August through October. I captured this one in my backyard in Rockaway, NJ. I used a Nikon Coolpix L110 digital camera.
