I just learned recently about cole crop moth/worms, otherwise would not have thought to look under the leaves, let alone determine the significance of teeny bumps... the imported cabbageworm does lay wee elongated whitish eggs, singly (so might see 1 or 2 on a leaf). Pics in this link: http://www3.telus.net/conrad/insects/icw.html For my potted crops, I don't have too many so looking under & just squishing the eggs actually worked. But in the (rather crowded) garden bed I haven't been so diligent - hence, more holey leaves (slugs also seem more active there). Apparently there are other such critters too; the link below doesn't have pics but does describe the moths, larvae, and where to find the eggs.

Polyphemus moth. I think it is a male. The antennae look too big for a female but too small for a male. I'm guessing they are at an angle that makes them look skinny.

It's a butterfly. Two things confirm this: the wings are folded up above the head at rest (moths typically do not do this, with some exceptions); and the antennae end in clubs. This individual appears most likely to be an Orange Sulfur or a Clouded Sulfur. Jeff

I put my $ on Diaphania nitidalis (Pyralidae), AKA pickleworm moth. It is a pest of squash, mellons, gourds, and cucumbers/pickles. Your first pic is a male extending his hair pencils so there should be a female in the immediate vicinity. KC Here is a link that might be useful: Diaphania nitidalis pics
