Having a Passion Fruit vine in our backyard inevitably attracted the Passion Butterfly or Gulf Fritillary (Doine vanillae). The caterpillars do munch on the leaves, but it didn’t seem to affect the plant very much — it was very productive, especially considering that it is potted and a couple of years old already.
Much to our amazement, we found two chrysalis hanging from the old wood of our patio cover pergola… and they’ve been there for what seemed like a long time (much much longer than the 11-21 days that Wikipedia mentions, but who knows?). In early January, one of the butterflies finished its metamorphosis, and a couple of days later, the second one.
