I found a wierd-looking insect inside my house and I don't know if it's a good insect (eats aphids or scale or other unpleasant bugs) or a bad insect ("harvests" aphids or scale or other unpleasant bugs or eats my plants). It is mostly brown and light brown and about 2 3/4 to 3 inches long and about 1/2 inch or less in diameter. It has a narrow waist, like a wasp, and the bottom half is striped, like a wasp or bee. It's wingless but has pretty long antennae--maybe an inch. I think it is injured, because it seems to favor the legs on one side. Anyway, I captured it so I could look at it closely (unfortunately no pictures, though) but I finally put it outside far away from my house to let it do its thing. Do you have any idea what kind of but it might be?

Thanks, Debbie
