This is one of many cats I found munching on my Passiflora 'Lavender Lady'.
Any idea as to its future (butterfly or moth)?

I had trouble with this one because the picture in my book looks different than yours. Searching the web I think it's a Gulf Fritillary. This link has good information about its life cycle. http://www.sasionline.org/fritillary/fritillary.html
Your passion vine collection should bring some interesting butterflies. There's many species that use passiflora as host plants.
