I'd been hoping to find some of the overwintering butterflies today, but it was not to be. However, I did see quite a few of the Smaller Milkweed Bugs (which overwinter as adults), some midges and other flies, micromoths, and several of these guys, the Winter Firefly, on trees. The adult is on the left of this image, and the larva is on the right. The larvae of this species, like most firefly larvae, 'light up' at night. The adult, however, in this particular species does not emit light. Fireflies, by the way, are not flies (as you can probably tell!), but are beetles. A very misleading name for them.
