Congratulations Christine, your locust borer has been voted Spotting of the Week! The series of images, information, mission assignment, reference, multiple tags and general interest of this spotting were appreciated.
"A serious pest to black locust trees (Robinia pseudoacacia), this Locust Borer (Megacyllene robiniae) is our Spotting of the Week. This longhorn beetle (family Cerambycidae) is endemic to eastern North America. Its geographic range has grown over the years with the expansion of R. pseudoacacia. Larvae spend the winter hibernating within the bark and start burrowing at springtime. With infestation tree trunks and branches can weaken and become susceptible to wind breakage.
