Cycnia collaris – Unexpected Cycnia

Hodges # 8228

Caterpillar foods:  certain milkweeds including Butterfly Weed and Whorled Milkweed (personal observation)

(Formerly Cycnia inopinatus)

Information on this species from Massachusetts

I find these caterpillars every summer, almost all of them on Whorled Milkweed (Asclepias verticillata) plants on remnant bluff prairies.

8/28/2011  Caterpillars on Whorled Milkweed





I took several of the caterpillars home, and fed them on Butterfly Weed (Asclepias tuberosa) and Whorled Milkweed (Asclepias verticillata).  I offered Common Milkweed (Asclepias syriaca) but they didn’t eat it.

9/8/2011  One of the pupae

3 pupae were kept over the winter wrapped in a paper towel, then placed in a clay flowerpot buried in the ground up to the rim, and covered with a clay saucer.  They were removed from the flowerpot at the end of March 2012, and put into a jar on my screened porch.

5/20/2012  This moth hatched with one deformed wing.  I think I had damaged the pupa when I moved it into the flowerpot last fall.

5/25/2012 – I released it into one of our remnant prairies.
