Bright sun and a fast butterfly make this one difficult for me to identify. Its overall look in person was small and beige. The blue showed when it flew. Is it possibly a Reakirt’s Blue butterfly, an Echinargus isola? Thank you! Mostly sunny, warm day today, and this is in a field of native grasses, saplings and wildflowers. Here’s the reference from Bug Guide: http://bugguide.net/index.php?q=search&keys=reakirt%27s+blue&search=Search
While we agree that this is one of the Blues in the subfamily Polyommatinae, we cannot say for certain that it is Reakirt’s Blue. This is a very difficult group for us to identify to the species level.
