Elderberry Borer

A recent image came in to the lab from the Wausau area of an adult elderberry borer (Desmocerus palliatus).  It gets its name from the larval stage which lives inside the stems of elderberry plants and bores down to the roots.  These beetles are members of the long-horned beetle family (Cerambycidae) due to their long antennae.  The elderberry borer happens to be one of our most distinctive species, although it isn’t spotted often.  It was even featured many years ago on a 33 cent US postal stamp.
