I dragged my family down a nature trail on a butterfly hunt, and we had to climb over a large fallen tree to follow the trail. This huge pair of mating beetles was very busy on top of it.  I was chasing butterflies, and had limited camera space, so unfortunately these are all the photos I got. I believe they're Neoclytus Mucronatus beetles, but I've emailed Guy Hanley to see if I'm right. I'll update if / when he answers, but in the meantime, if you know, let me know what you think.
