Dear Ryan,
We quickly identified what we suspected were Giant Bark Aphids, Longistigma caryae, on BugGuide, but there were no images of what we suspected might be eggs. The Bug of the Week site has a nice image with the caption: “Eggs of the giant bark aphid are the overwintering stage. They line small branches by the thousands and change from amber to black as they age.”
