The World’s Smallest Butterfly

By Janice VanCleave

butterfly-western-pygmy-blueHow Big is the World’s Smallest Butterfly?

First, let me name this tiny insect. The Western Pygmy Blue is the smallest butterfly.
Now about the Western Pygmy Blue’s size. When spread out, its wingspan is about 15mm to 19mm.
Just how big is this?

Discover for Yourself

Use a metric ruler to draw two lines, one should be 15 mm line long and the other 19 mm.

These are very short lines and it is hard to imagine a butterfly being that small, but the Western Pygmy Blue is.

Physical Characteristics of the Western Pygmy Blue 

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 seem to have more blue than the one shown. But then, often there are 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.

While  researching butterfly projects for his school’s bug club, Elliot found the information on this page very helpful. Elliot also found the following butterfly guide and suggested that I share the link with others. I agree with Elliot, the information on this guide is great.

A big thanks to Elliot.
