Life Cycle

On Ned's Nature Walk of 2/18, Fred spotted a Pipevine plant (Aristolochia watsonii) with eggs from - that's right - a Pipevine Swallowtail butterfly!

Click on this photo and note the red circles that Marty drew around the red eggs.

The next week (2/25), Gene did some fancy acrobatics to get a shot of two tiny caterpillars that hatched from the eggs above.

After the caterpillars grow a bit, they look like this. The caterpillars feed exclusively on the Pipevine plant. After they've grown large enough, they pupate, i.e., they cover up, take themselves apart, and reassemble as Pipevine Swallowtail butterflies. That's what we call complete metamorphosis :-)
