acastelein's Identifications

Saw it lying across the trail, but when I got close with the camera, it immediately flipped entirely over to show it's orange underside.
I'd not seen that behavior before. The few I've found in the past would just show the bright red tail curled up.
I guess that these are defensive/distraction behaviors, though I have trouble understanding how making part of yourself look more like a fat juicy worm would be at all helpful in most cases.

I tried getting one more photo as it quickly took off, but I wasn't fast enough to get a good shot.
