It's my first sighting and first post so I'm the newbie. It was probably more like 70mm! Can I change the listing? And it was special because we live on Ulysses Cct but Swallowtail Rd runs parallel!
I'm jealous that you even got a photo of one, I've currently got 548 butterfly sightings on CNM and not one single Orchard Swallowtail adult flying, only the larvae.
Yes, the other photos came through, very nice! This butterfly often lays its eggs on citrus plants such as Lemon or Mexican Orange, so if you have those in your garden, keep an eye out next season for the caterpillars.
