Comments:
This is our most common crescent and it can be found underfoot about anywhere.
Generally in most of the region this will be the only orange crescent
found during spring unless you are along the coast where the tiny Phaon
Crescent can be found.
In May the larger and darker bordered Silvery
Checkerspot shows up and could be confused with the Pearl Crescent.
Examples of spring and summer form specimens are shown at right showing
a great deal of variability. Given all the variability I chose not to
give pointers to identification marks on this species.
