I'm looking at the various likely species of Blissus, and (as a very very amateur entomologist), I can't tell the difference among insularis, leucopterus, and occidus. They've all got the same white wings with a black triangle, red-brown legs, slightly clubby antennae...does anyone know what I should be looking at, to figure out for sure which mine is? The only real clue I can think of is size; this guy seems full-grown, but he was only 2 or 3 mm long. Thanks!
