Use a metric ruler to draw two lines, one should be 15 mm line long and the other 17 mm.
These are very short lines and it is hard to imagine a butterfly being that small, but the Western Pygmy Blue is. As you can see in the photo, the wings of the butterfly are multicolored. But basically its dorsal wings are golden brown with blue close to its body. Some of them appear to have more blue than the one shown. But then, often their is some changes in their color depending on the angle of the light. Their coloring is due to tiny overlapping scales on their wings.
This tiny beautiful butterfly can be found throughout the southern United States usually close to the coastal areas.
The Western Pygmy Blue can be seen all year long but is most often seen in early July through September during the warm weather season.
