Summer Azure Butterfly
Celastrina neglecta
Aka Summer Azure, Holly Azure
Family: Lycaenidae/ Subfamily Polyommatinae
This butterfly is part of what has been called the “Spring Azure Complex” – that is, several species of butterflies so closely related and similar in appearance that even experts have trouble telling them apart. They are variously known as Spring Azure, Summer Azure, Hops Azure and Holly Azure, et al.
Until recently, all North American azures were thought of as one wildly variable species, and their classification is still being studied.
