I used to have trouble finding this beetle, but this past spring I realized they come to this flower fairly commonly, but have to be searched out carefully, as they look like a little bit of dead flower. I found several in just a few minutes of searching. Much of their lives is apparently spent in association with termites, but they do come to flowers in spring--I presume as they disperse in search of mates. This one is on Downy arrowwood, Viburnum rafinesquianum.PCCA20080425-0858A
