Hi, I like walking through the Great Marsh in Beverly Shores, IN. It is part of the Indiana Dunes National Lake Shore.
I came across a Pearly Wood Nymph which I thought was fascinating. I have included pictures of that. But my question is about the black and red, feathery looking bug. I found it in the Marsh as well. I have never seen another of either bug since then. Thank you.

Grapeleaf Skeletonizer

Hi Janet,
The insect you would like identified is a Grapeleaf Skeletonizer Moth,
Harrisina americana.  According to BugGuide, the adults are nectar feeders and they are unusual in that they are both nocturnal and diurnal.  Caterpillarsfeed in groups on the leaves of grapes, eating them to the veins.  The Pearly Wood Nymph does an excellent job of mimicking bird droppings.

Thank you so much. I am so glad to have discovered this site.
