Silvery Blue Glaucopsyche lygdamus

Fine genus name. Sounds like glow-in-the-brain. This is a butterfly to make a butterflier out of anyone. A flash in the springtime only. Arkansas has the Appalachian form along with the lucky folks in the southern Appalachian Mountains. Occurs in AR only in a west central stripe of mountainous counties. Males like this individual are iridescent blue from nearly black edge to black edge inside. Females have gray boundaries around the blue. Often found puddling on clear sandy or gravel-lined creeks with Spring Azures. This one is enjoying a Spring Beauty, Claytonia virginica, bloom in May.

The western blues are more diverse than the eastern group. Tends to happen in mountainous terrain. This is Boisduval's Blue which resembles the Silvery. Very variable. This is the male interior. Exterior is very similar to the Silvery. Larger black borders on the interior blue of the male than in the Silvery. From the rockies in Colorado.
