So far this year I’ve seen no black swallowtails in the yard. We’ve had more small skippers, and the past 2 Sundays brought a silver spotted skipper. But I have seen a few tiny white spheres on the fennel. They looked a lot like butterfly eggs.
Today I saw this new fennel resident. It certainly looks like an early instar black swallowtail caterpillar! But I still have seen no adults.
