I have killed three extremely large bees/hornets that I have never seen in western NY. Concerned about safety of my grandchildren with these pests showing up occasionally. What are they?
The picture did not get posted, however from your description it sounds like the European hornet, Vespa crabro. See https://en.wikipedia.org/wiki/European_hornet for some general info and pictures. These hornets are very similar to our native yellowjacket wasps just larger. They are no more (or less) dangerous.
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
