Hey there! Oakworm (or so I think I remember) season is just starting around here, and most of the small oak trees at the park are ALREADY defoliated! Oy, it’ll be a bad year. Anyhow, I am curious if these are eggs coating the underside of the leaf or something else. It was very pretty, in a creepy sort of way.
These Oakworms are the caterpillars of moths in the genus Anisota (see BugGuide). When they are really plentiful, Oakworms can defoliate trees. It is our theory that the eggs, yes they are eggs, in the photos are also Oakworm eggs, but alas, when they hatch, they will not have anything to eat. Thanks for sending us your great photographs.
