Thanks, we are surrounded by MD, NJ and PA; none of them show this butterfly in October so I probably caught the last one in September.

I've never seen one with both the "hairs" curled upwards. Generally, they turn away and rub wings together to ward off evil intruders - me - with their fearsome appearance. (The effect is supposed to be a creature with a huge orange eye and large antennae.)

Did it stay this way for a period of time, or did you catch it withj wings in mid-rub? (Your other photo shows a typical pose.)

I don't remember it posing for me. Probably was moving its wings so its more like a lucky shot.

I'll bet the reason that both tails are sticking up was because there was a slight breeze blowing in that direction. I've seen it happen before:

It was windy the day I took this picture. It's always too windy here.

Now I can retire my wind sock.
