We seem to have had an ’infestation’ of sorts for the past month. I don’t know how they are entering the office, but we are on the 2nd floor and there are quite a few trees outside. These guys fly around, are up on the carpeted walls, or in boxes. They bite each other’s legs off if kept in the same container.

Hi D,
Perhaps you have some new construction or new furniture at your office and wood that was infested with Stout’s Hardwood Borer larvae was used as a raw material.  Your observation that they bite each others’ legs off might explain why this Stout’s Hardwood Borer from our archive and this individual that our editorial staff photographed are also missing legs.  It is possible that males battle with one another for dominance.
