Aerva and Argalis are my favourites so far. The alliteration is a good addition to the more obvious patterns, and makes for a solid progression of names. I wouldn't mind seeing Cuptera and Agrelia win the polls either.
I'm not a fan of submissions that give "pupa" names to the first stage, when the second stage is the actual pupa. I know "cuprum" and "pupa" combine well, but calling the larva a pupa still bothers me. A minor complaint maybe, but I don't think I'll be voting for any that do this.
