PEARL CRESCENT – YET ANOTHER REASON TO GROW ASTERS (as if we needed one!)

Life at the Edge of the Sea – Pearl Crescent Butterfly

Seen throughout the summer, the beautiful female Pearl Crescent on the asters is from my garden just a few days ago. Pearl Crescents drink nectar from a great many flowers. On the smaller side, with a wing span of about 1.5 inches, they are not always easy to identify because their wing patterning is highly varied. The composite photograph below is from wiki and shows some of the many variations.

Grow Native! Pearl Crescents are found throughout North America, wherever asters grow. Asters are the caterpillar’s food plants and according to Mass Audubon the species of asters they are known to feed on in New England are: Heath Aster (Aster pilosus), Many-flowered Aster (A. ericoides), Bushy Aster (A. dumosus), Calico Aster (A. lateriflorus), Whorled Aster (A. acuminatus), Smooth Aster (A. laevis), Panicled Aster (A. simplex), Purple-stemmed Aster (A. puniceus), and New England Aster (A. novae angliae).
