Mournful thyris (Pseudothyris sepulchralis) resting under rock
This is a mournfulthyrsi, a colorful, day-flying moth found in forests throughout the eastern US. As caterpillars, they feed only on the leaves ofgreenbrier (Smilax), a thorny vine that often irritates hikers. It’s fun to associate an attractive day-flying moth like this with the thorny plant that many curse.
