Meeting: Pipevines and the Butterflies That Love Them

Pipevines and the Butterflies That Love Them, presented by Dan Hardy, Ph.D. This lecture will explore the fascinating ecological relationship between the Pipevine Swallowtail-group of butterflies and the special plants they use for caterpillar food plants.

The Pipevine Swallowtail is the commonest dark-colored swallowtail in Austin, but it's native caterpillar food plant is an obscure grass-like plant hidden in the fields around us. That plant is poisonous, but the caterpillar overcome the poison and turn it to its advantage. We will use that biology to explore defensive chemicals, mimicry, host-plant relationships, and evolution. From Austin we will roam through Mexico, South America and the Old World to find other butterflies that use the pipevine. In addition, the pipevine plant's biology, pollination, flower structure, and folk medicine uses are fascinating in themselves.

You may arrive up to 15 minutes early to chat with other bug lovers. The meeting begins shortly after 7pm. We start with members sharing observations, do a little bit of club business, and then begin the presentation. The presentation is usually an hour long, and we're typically closing the meeting between 8:30 and 9:00pm.

Your RSVP is not required, but those who RSVP will receive email reminders and allow people to learn about other members.
