Sat down to wait for Mickey to chase squirrels and found these two beetles mating this morning. I put a plastic jar over them and ran for my camera. They were still mating. I had enough time to take this one shot before the male began withdrawal.
The female then left a drop of yellow on an oak leaf. Beetles, I believe, deposit eggs in the ground so I don’t think it was an egg, but perhaps excess fluid from the male.
