Size: approx. 1 inch
Found in a wooded area of a park.

Family Cerambycidae
It belongs in the family Cerambycidae, the Long Horn beetles!
As you can see there are species with very short elytra, like a rove beetle!

Looks like Necydalis mellita--moved to guide
Neat Gerard, I would have thought that was a rove beetle. Looking at Yanega (1), it looks like Necydalis mellita shown on plate 15, figs.174a, b, descr. pp. 28-29. The pronotum is constricted, I think visible on this photo. Body very long and slender--he says it is a wasp mimic, very interesting.

Image at Florida Longhorns, and of course here. This looks like a female, according to the illustration in Yanega, and comparing the other photo in the guide, of a male.

OK, those look good, I'll go ahead and move to a guide page. Excellent photo, incidentally.

Thanks for the ID and the compliment!

It flew slowly past me at just before sunset when the light is tricky and at first I did indeed think it was some kind of wasp.
