Western Pygmy Blue
Well, I think it is a Western Pygmy Blue. The spots on the upper surface of the wing make it look more like an Eastern Pygmy Blue to me, but that one doesn't occur in Texas. The WPB the smallest butterflies in the world, about 5-7 mm. It occurs in salt marshes and eats salt bush as a caterpillar. It also lives in other salt areas and eats other plants in the goosefoot family. I'm glad I finally got a good look at this butterfly because now when people ask me about the smallest butterfly in the world, I can say that I have actually seen it.
