The gulf fritillary caterpillar will eat between 11 to 16 days to reach the correct size to create its chrysalis. This guy is nearing the end of the final instar.
With the maypop passion vine popping up all over the yard, outside of the garden, it has been easy to feed the caterpillars that are residing in the butterfly house. They do not discriminate against any part of the plant – once the flowers and leaves are gone, they go after the stem of the plant.

And of course, what the caterpillar turns into after emerging from its chrysalis. A gulf fritillary butterfly.
