The Blues are small, exquisitely beautiful butterflies that are usually colored blue (on the top of their wings). The disposition of this butterfly is very apparent as you try to get a closeup.

Sometimes they will not stay on a desired flower longer than a few seconds because they're chasing off anything that looks like another butterfly. Skippers can get near at their peril. There's a crazy little guy in a butterfly suit that will fly in their face until they leave.
