This was found in an otter scat and I believe it is an organ in a fish or in crayfish but I'm hoping someone might have more information on it. Possibly used for sensing water pressure.
Spent much of its time hovering a foot off the ground.
My guide shows three different all-white tiger moths: Spilosoma latipennis, Spilosoma virginica, and Hyphantria cunea. I didn't try to view the underside for any markings there.
This pair seemed very interested in each other. Courtship?
Pair courting. The male (on the right) would vibrate his wings, and the female hopped around a bit.
