On Dwarf Chestnut Oak (Quercus prinoides)
I am not sure about these. They were very small, and the heads very black. Erynnis brizo should have one large spot on top if the head, and greenish yellow coloration, more like E. juvenalis. Perhaps this is normal for early instar E. horatius from late in the summer brood.
