Mating Broad Necked Root Borers

Dear Randall,
We are most excited to post your photo of mating Broad Necked Root Borers,
Prionus laticollis, our featured Bug of the Month for July 2011.  The larval grubs feed on the roots of trees, but they are not considered a pest species and it is doubtful there would be such a high population on a single tree that they would negatively impact the health of the tree.  Root Borers have very strong mandibles, and though they are not an aggressive species, should they be carelessly handled, they might deliver a painful bite and possibly even draw blood.
