We’re more than a week into May now, so it’s likely you’ve seen the tigers and tents that first appeared in late April. If you haven’t, here’s who they are.
Tigers
I first noted tiger swallowtails at Enlow Fork on 25 April but I remember seeing one earlier in Schenley Park. When was your earliest tiger swallowtail?

I saw the first tentworms on 30 April in Frick Park, but it seems this is not a big year for them. I haven’t seen many other tents. Did you know that tentworms are a favorite food of yellow-billed and black-billed cuckoos? Have you seen a cuckoo yet?
