Long-horned beetle, Orthosoma brunneum. Grubs bore in trees, but are not present in large enough numbers to cause serious problems. Can give a bad bite, but is not aggressive. Leave it alone, and it ought to leave you alone. Good flyer, and from what I've seen, more active at night.

Yes, that looks exactly like what I've got.... thanks so much for the quick ID! (I'm so used to hearing "Asian" in front of "long horned beetle" here in the Northeast...good to read about this one, which is a native and apparently "beneficial to the composting process" according to something I just read from the CT Ag Station). I just checked and it's still in the same spot, but I'm hoping it will be gone by tomorrow, otherwise I will have to gently relocate it to the woods. It is one impressive looking beetle!

I found a giant bettle with pinchers in CT. Any ideas what he is??

One of the Stag Beetles, family Lucanidae.
