|This one is a flower longhorn beetle, Xestoleptura crassicornis.|
The glossy elytra (wing covers) and the orange antennae are diagnostic features.
BugGuide has about 3,600 photos of beetles in the flower longhorn family, about half of them decked out in vivid colours, reds and orange and yellow. I wonder if these are a sign to birds that the beetles taste bad, as is said about some other insects.
But then again, we're just guessing at that, aren't we? Maybe there is no reason at all; it's just the way things happened.
Any volunteers to taste a pretty beetle? I've lost my appetite. Or I'm allergic. Or my taste buds are old. (Any excuse will do.)
