Zebra Longwings

I bought a trellis for the passionflower vine and took a closer look at the caterpillars on it. They are mostly white with a little orange tinge on the underside, black spines, and speckled with black.  They are still tiny, but are obviously different from Gulf Fritillaries.  GFs are orange with a black line down their back.  Not much if any white (unless they are the albino version, which still has the dark stripe down the back).

These are Zebra Longwings (Heliconius charithonia)!  I'm excited!  I hope my small vine can give them enough food though...

My native garden looks untidy (it could use hand weeding, but it's never ever mowed), but most of what you see there is Coreopsis, Passiflora, and Aquilegia.  Native magnolia leaves make OK mulch but probably hold a little too much water for my mosquito-disliking self.
