ID Longhorn Beetle

19 years ago

Sorry - no camera with me at time of sighting.

This morning, while hiking in the woods in Fairmount Park in Philadelphia, PA, I came upon a large, black longhorn beetle.

It was about 1 1/4 inches long, its antennae curved back and were about 3/4 inches long and segmented. The beetle was totally black, and was clinging onto a leaf of a tree, about 4' up from the ground. I did not notice the type of tree. So far, my Internet searches of beetles have come up with nothing.

Any ideas?

Thanks,

CarrieB

Sounds like it might be a species of Prionus, which are root borers. Most of them are large and all black. Check out the link below.

Thanks Tucker,

It certainly looks like Prionus, perhaps Prionus imbricornis. Based on my limited Internet research, it looks like they spend their time in and around roots, and that they are nocturnal. Is it unlikely that I would have spotted this guy 4' up a tree at around 9am?

Thanks,

CarrieB
