I found about 10-15 of these beetles making holes in a still-standing dead elm (only about 15 feet of the truck was still standing). The ones that were making the holes seemed to be females (though I didn't see the antennae on all of the ones making holes -- only if they pulled out, which some of them did now and then). The only definite male I saw (impressive antennae) was marching around on the trunk. I brought him and one female home to get clearer photos. This photo above is of a (presumably female) beetle making a hole in the trunk.
