Can you believe the colors on this moth?

Fuzzy pink and yellow, the rosy maple moth (Dryocampa rubicunda) lives only a week in this beautiful body. Its wing colors are highly variable but its head and back are usually yellow with pink belly, legs and antennae.

Most of its life is spent as a green-striped caterpillar, eating maple leaves, and passing through five instars.  When fully mature the caterpillar crawls down the tree and pupates underground.

In western Pennsylvania the moths are above ground from May to September but are easiest to find in late July.  The adults don’t eat.  They have only one job, to procreate.

The action begins around sunset.  The females perch on the undersides of leaves and exude pheromones.  The males fly around “sniffing” the air with their big fluffy antennae.  Perhaps this division of labor is why the females have insignificant antennae.  (My guess is that the moth in Don Weiss’ photo is female.)

If you’re lucky to see the rosy maple moth you’ll be surprised at how small it is — only 1″ long. Click here to see one on the tip of a finger.

I found one once at the Panhandle Trail in Collier Township.  Its beauty stopped me in my tracks.

  5. A friend who saw one in Northern Durham County, NC in July 2019 on the side of her house said it was 3 inches long. (Since she is a seamstress, she may have a good eye for measurements.) It would be helpful to post a photo of the caterpillar. Have you ever seen one?
