Clear eggs are usually duds, eggs that, for whatever reason, were infertile and didn't hatch. Zebra longwing eggs are yellow, according to my books. I've never seen ZLW eggs, so I don't know if they look like gulf frit eggs or not, probably do. ZLW cats look like gulf frit cats in the early instars, then become white, whereas gulf frits stay orange. Congratulations! Sherry

I get both Fritillaries and Zebras on my subarosas. These vines now come up in many places on my property. The Frits like the passion vines more, however. I now have this huge infestation of Mexican Flame vines (Pseudogynoxus chenopodioides). They are covering many of my other plants. I'm going to wait until they stop blooming before I try to rip them out again. For now the butterflies are loving them. I'm seeing quite a few Giant Swallowtails for some reason. I have seen only a few Frits, but quite a few Sulfurs, some Monarchs and some Polydamas. I haven't seen a black swallowtail or a Pipevine yet.

A follow-up. The eggs have hatched. After extensive research and a post to some good folks at a bug identification website that I frequent, I can positively say I have caterpillars of both species. I am just going to let them live. I can't bring myself to destroy them and chances are, they won't survive long on their own as adults up here, so there is little chance of invasion (although I would never consider them invasive, even if they are not native here).

Where are you getting these? Are you buying them? Good to see a healthy one.
