This is a European hornet (Vespa crabro). It’s also dead. I found it on the floor of the basement when I stepped on it in my bare feet, which worried me a little. It was mostly dead before I stepped on it and completely dead after that. Since I didn’t get stung, I’m over it. They are predatory on other insects so in general (and outside my basement), I have no problem with them being around. They are similar in size to the eastern cicada killer (Sphecius speciosus) but are quite different in appearance. As large as they are, the European hornet is smaller than the Asian giant hornet (Vespa mandarinia, sometimes referred to as murder hornets), which can be 30% to 50% larger.
