Carroll Mill Road photo is a small worn female. The underside shot shows the features needed to distinguish Silvery from a Pearl Crescent. The light-colored submarginal band is very wide. In addition, always look also for a white center in at least one of the black marginal spots. Usually the white center is visible in the spots on the upperside too. All Silvery Checkerspots have a white center in one of the underside hindwing spots. Pearl Crescents never have this, upperside or underside.

Individuals seen in each 10-day period to date during the butterfly survey

The phenograms show the maximum number of individual butterflies of this species seen in the first eight years of the Howard County Butterfly Survey. From these graphs, one can see the number of broods of each species, when they are active, and the relative abundance of the species in each brood. The observed early and late dates are shown below The graphs can be used to anticipate the first sighting of a given species in the year and can help with identification.
