Great Spangled Fritillary has finally shown up, visiting the Butterfly Weed.
Rusty Patched Bumble Bees.
Spicebush Swallowtail although I've seen a few off and on for a couple weeks. It's a female, from the blue wash on the hind wings.
Zabulon Skipper on the Verbena bonariensis. A perennial, it also seeds freely, and forms thick stands readily.
Male and female Zabulons are so different you might mistake them for different species.
Clouded Sulphur. Only females come in the white version. Easy to confuse with the white trash of butterflies, the Cabbage White.
