Female Tiger Swallowtail (note the blue on hindwing) is one of Ohio's most spectacular insects. A color scheme almost too much to believe... a tiger-striped butterfly! Seriously! Nectaring on Purple Coneflower, Echinacea purpurea, this plant is irresistible to the fliers- both butterflies and finches.
The Swamp Milkweed, Asclepias incarnata was really hopping. Here is a Giant Swallowtail and a Monarch nectaring on the same plant. This is also a host plant for Monarchs, so it would be a good place for her to lay eggs as well.
One more Joe-Pye customer, a Summer Azure (female- has darker outline on dorsal wings) is a mini-lep, smaller than a dime. Summer Azures are a bit lighter or whiter than the Spring Azure, and they may be smaller in size.
