Spring Azures are more heavily marked with black on the undersides of the wings and are a little smaller than Summer
Azures. They are common from late February until late March/early April. I found a male flying as early as
January 28, 2006 in Upson and found another in Upson on February 11, 2008. The first large brood of Summer Azures emerges
in late April and later broods fly until September. Recently, I have seen a few Summers on the wing during the flight
of the Spring Azure and have found an individual resembling a Spring Azure on April 27th. I'm just can't convince
myself that these represent separate species, they seem more like seasonal forms.
Measurements from my specimens indicate the following lengths:
Wingspan: (Spring Azure) Approx. 1 1/16
Wingspan: (Summer Azure) 1 1/16 to 1 1/4 in.
