Thank you Kate for the Black Swallowtail Chrysalis!
Last week while filming on Eastern Point I had the pleasure to meet Kate, who works at Wolf Hill. She was with a friend and they were looking for butterflies through binoculars. I had seen Kate often at the garden center, but never stopped to chat. We were talking about all things butterfly when she mentioned that she had a Black Swallowtail caterpillar on a parsley plant back at the nursery office. She offered the caterpillar to me and I gladly accepted. My Black Swallowtail film is nearing completion but there was one missing piece to the story.
The swallowtail chrysalides that I had on film were all greenish gold. Oftentimes the Black Swallowtail chyrsalis will turn a woody brown, but no matter how hard I looked, I could not find a woody brown chrysalis. Not showing the brown form, I knew, would confuse viewers, especially families who are interested in raising swallowtails.
Kate’s caterpillar pupated while she was away from work for a few days. When she returned she found the chrysalis had wandered from the parsley plant and it had pupated on the razor thin edge of an envelope-as office caterpillars are want to do. Well, you guessed it–the Wolf Hill pupa was the brown form!
I know it is said often on the pages of this blog, but Kate’s thoughfullness goes to show once again what a beautiful community is Gloucester–stunning visually, and most special of all, are the beautiful, kind-hearted people who call Gloucester home. Thank you Kate!
Not finding a brown chrysalis is a relatively escoteric problem, to say the least, but I think you will agree that the two forms of the pupal case are remarkably different in appearance. In this photo you can see where I have taped the envelope behind a tree trunk in order to film. This is how you would find the chrysalis in a more natural setting.
There are several openings remaining in my Close-up Photography Workshop at the Arnold Arboretum of Harvard University, which will be held this coming Sunday morning at 9:00 am. I would love to see you there! Follow this link to register.
Capturing a sharply in focus close-up of a butterfly, especially one in mid-flight, is one of the greatest challenges of photography and I will be revealing techniques such as these, and more; techniques that have taken many, many hours over many years to perfect. All the photos I have shot in the past year and a half were taken not with a zoom lens, but were shot with a 23mm prime lens. I am typically photographing within a foot’s distance of the butterflies!
