Hello! You have a great site. I have used it many times this summer. I was wondering if you can tell me what these bugs are. Are they a type of wasp? They have been stripping the bark off my lilac bush – I’m assuming they plan to lay their eggs there. Any id help would be appreciated.

These are Giant Hornets, Vespa crabro germana. They are found in the east. It is an introduced species. These are social hornets that build a nest in a hollow tree, under porch floor or in and outbuilding. The females in your photo are gathering bark to chew into paper pulp for the nest.
