I stopped by their nursery today hoping to buy the caterpillar, um, I mean a host plant with the caterpillar on it, but I didn't find one, and they said they hadn't seen another visit them after this one emerged and flew off on their property.
They aren't as common as many of the other butterflies readily available there. I'll check back with them another time, and perhaps I'll get lucky and find one.
I've read that they'll use Passiflora incarnata. I wonder if they use Passiflora suberosa too? Email me if you know for sure, and I'll update this page after I find the butterfly.
In the meantime, my other butterfly pages are much more complete, so have a look at those.
