Beauty on the Wing ~ A Luna Moth takes Flight
My friend James, the facilities director at Willowdale Estate, sent a photo of a newly emerged moth on Sunday afternoon. He initially thought it was a paper napkin stuck to one of the lampposts, but upon inspection, discovered that it was a Luna Moth (Actias luna). With high hopes the moth would still be there, I dropped everything and raced over to Willowdale to photograph and film the moth. It is not that the moths are particularly rare, but that they are most often seen in flight at night. Lucky me, to have had such a wonderful encounter with one of the most beautiful moths in all the world!
The Willowdale Luna Moth is a male of the species; you can tell by his bushy and feathery plumosa (or antennae). The female’s antennae are more thread-like. Notice too, just before he takes flight, how his body vibrates, which helps warm and energize the wings in preparation for flying.
Luna moths are members of the Saturniidae, subfamily Saturniinae. With a wingspan of typically up to four and a half inches, atypically up to seven inches, they are one of North America’s largest moths. Luna Moths are most often seen in the earlier part of summer in our region; this Luna Moth encounter took place on August 11, 2013. Luna Moths, like all members of the Saturn family of moths, eclose without mouthparts. They emerge solely to mate and deposit eggs of the next generation and live for only about one week.
Luna Moth larvae (caterpillars) feed on wide variety of broadleaf plants and different geological populations of Luna Moths are adapted to different hostplants. Northernmost populations most often feed on white birch (Betula papyrifera). More southerly populations feed on persimmon (Diospyros virginiana), sweet gum (Liquidambar styraciflua), hickories (Carya), walnuts (Juglans), and sumacs (Rhus).
The damage done by Luna Moth caterpillars on host trees is never significant enough to harm the host trees. Please don’t spray your trees with pesticides or herbicides!
A note about the music playing in the background ~
