Hi, I just came across this beetle today on my patio screen door. It resembled a spotted one I saw earlier on May 16. I thought it was the same type. However I knew it was different when it picked up its head and I saw its antler-like antennae. I met this beetle earlier in the week actually. I remember poking its significantly longer hind legs with some straw. They are hooked, and very strong. Something you may be able to see from a few pictures is that this beetle seems to drag its long hind legs. When on a smooth table surface these legs seem to be more up in the air. When I dropped it outside on an uneven concrete surface, the legs were much closer to the ground, as if scanning the concrete. They did not seem to aid in locomotion. This particular beetle had very fluid head/neck movement as well. It stopped when I was hunched over it and curved its head upward gently. This is a winged variety of insect as well. Upon looking at the coloration of
the shell, this is not the same beetle I saw on May 16. This one also had a more pronounced legs, head, and antenna.
You can find these beetles in the 'NJ Beetles' folder in Identity1. Thank you.
