Coordinator notes: Aner, this is Ceraunus Blue. It is very similar to Reakirt's Blue, same size, etc., but if you examine the forewing underside you can see that your individual lacks any of Reakirt's white-ringed black spots. Ceraunus is much less routine here than Reakirt's, but it does diffuse into southern NM with some regularity in late summer. It's fun to see it!
