Your letter to the bugman: Hi Bugman,
This large fly (about an inch long) has been hanging around my deck for a few weeks. It has an unusual habit of repeatedly darting at the railing when it hovers near the wood. I am usually able to identify insects on-line, but have not had luck with this one.

Dear Inconsistent naturalist,
This is a Tiger Bee Fly and we get numerous identification requests for them each summer. The female Tiger Bee Fly lays her eggs in the nest of Carpenter Bees, which might be the reason this individual is hovering year your wooden railing. We love your action image.
