I opened my window yesterday evening and a bug came flying in. With the loud drone of its wings, I initially thought it was a wasp and backed away. But it turned out to be a western conifer seed bug (Leptoglossus occidentalis).
This bug started out in the West (hence its name), but has since spread to the eastern U.S. and even Europe. They love to find their way into homes in the spring and fall. Apparently this bug didn’t get the memo: it’s still summer!
