Hi,
Here are three butterflies I hope you can identify taken a couple weeks ago. Are they all blues?

Lycaean Blue

Dear TerryDarc,
Yes, all of your butterflies are Lycaean Blues, and furthermore, we suspect since they were all flying at the same time in the same vicinity, they might all be the same species.

Female Lycaean Blue

The individual with the brown wings is a female.  Many of the Blues have pronounced sexual dimorphism with blue males and brown females.  In our opinion, two likely candidates for species are Boisduval’s Blue, Plebejus icarioides, which can be found represented on BugGuide, and the Greenish Blue, Plebejus saepiolus, which can also be found on BugGuide.  It is also worth noting that there are many subspecies and local variations in coloration among the Blues.  BugGuide notes:  “A varied group, and several species can be confusingly similar.”  The Thumbnails on the Butterflies of Americawebsite might help to determine the species.

Lycaean Blue

Thank you very much, Daniel!
-Terry
