Sulphur butterflies are quick, quick, quick

Note the long front legs, which make walking easier.

Here, there and over there.

It would be smarter to shoot video of the Sulphur butterfly than try to get a good still with a camera.

These little yellow fliers are so quick.

The rapid flights are mostly males looking for mates, according to Butterflies and Moths of North America.

The Sulphur family is a big group of yellow butterflies. There are Clouded Sulphurs and Cloudless Sulphurs.

A common one in Texas is the Cloudless Sulphur. And don't forget the Orange Sulphur.

They are about the size of a quarter.
