Monarch, Captive-Reared
Sightings report image

Date: 09/23/2020

Number: 2

Two monarch adults emerged from their chrysalises and were released to the environment. They were raised in an outdoor protective enclosure containing live, potted tropical milkweed and butterfly weed plants, and the enclosure was made around the plants after caterpillars were noticed on the leaves on August 23, 2020. They had formed chrysalises on Sept. 1 and Sept. 2, 2020. 5 additional chrysalises remain in the enclosure.

The potted milkweed is growing outdoors and eggs must have been laid by wild monarch(s). I built a screen enclosure around the planter when I noticed live caterpillars on it but the planter remained outdoors and the caterpillars were not moved in any way, and they stayed outside through thunderstorms and chill weather. They formed their chrysalises on the screen enclosure and after they (7) were all in chrysalid form, I cut away sections of the screen and the first 2 have emerged and departed of their own accord.
