‘Summer’ Spring Azure

Celastrina ladon neglecta

The ‘Summer’ Spring Azures are much lighter than the ‘Spring’ Spring Azures below. They look significantly different than the earlier flying subspecies, fly at a different time and are double-brooded. There are enough conflicting reports about the natural history of these species that it is clear that no one really understands completely how these taxa are interrelated. I think that the experts will be arguing about this for some time to come, and I will just continue to enjoy watching these lighter Azures that appear in early summer.

This subspecies is listed as the Summer Azure (C. neglecta) on the Butterflies and Moths of North America web site.
