This past autumn I wrote about a Black Swallowtail caterpillar that was discovered munching on the parley plants at Wolf Hill Garden Center in Gloucester. The caterpillar had left the parsley plant and wandered around the office at Wolf Hill, where it had pupated, or in other words, turned into a chrysalis, on the razor-thin edge of an envelope. By chance, I met Kate, who works at Wolf Hill, one afternoon at Eastern Point while I was filming Monarchs, where she and her friend were looking at the butterflies through binoculars. She asked if I would be interested in taking care of the chrysalis over the winter. I of course said I would be delighted to do so!
The butterfly chrysalis lived in a terrarium all winter. The terrarium was placed in an unheated entryway. I thought it best for the chrysalis to experience normal winter temperatures rather than live in a heated home where it might be fooled into thinking it was spring. In the early spring we brought the terrarium onto our unheated front porch so that it would be exposed to both the normal outdoor temperature and daylight .
A stunning male Black Swallowtail emerged last week. Earlier that very day I had seen a female Black Swallowtail nectaring at azaleas at a farm in a neighboring town. See the original post on Good Morning Gloucester about Kate and the Wolf Hill caterpillar.
