|5/11/10: Since the last date, approximately 5 more have hatched and been released. We are monitoring the egg laying on the Aristolochia, and after the caterpillars hatch and grow to about 1/2 inch, we capture them, and place them in special rearing cages. They eat a lot of larval plant, and we are always busy picking and feeding. Right now we have about 200 "buggers" in the cages with another 100 or so scattered about the property. Adults (male and female butterflies) are still cruising the plants looking for opportunity.
Comment as of 4/4/11: Weather has played a significant role in the hatching and releases of this season: heat in January encouraged early hatching followed by extended, heavy rains. Although there are several dozen more that may hatch, we currently see none cruising the yard, as compared to prior years at this time when female egg-laying was very active.
