Living With Celastrina


Azure, Celastrina spp.

Yesterday, I saw several Azures, Celestrina spp., fluttering into the woods and back out on the edges. Celestrina is a genus containing multiple species that are difficult to distinguish on physical appearance alone. Every state in the Eastern US has multiple species, some as many as five. There are 8 described species in this genus.

Most caterpillars in the genus Celestrina feed on flowers such as bugbane (Cimicifuga racemosa). The adults will collect nectar from a variety of plants including common butterfly garden plants. The butterflies are among smallest butterflies and are not as showy as Monarchs or Swallowtails. They have a delicate beauty when observed closely. Look for their beautiful azure blue wings in your butterfly garden this summer.
