Wing span: 1 3/8 - 2 inches (3.5 - 5.1 cm).
Caterpillar hosts: Many different composites including black-eyed susan (Rudbeckia), sunflowers (Helianthus), and wingstem (Actinomeris alternifolia).

The Silvery Checkerspot identification is easiest when looking at the underside of the wing. Look to the
difference in the moon spots, with the missing moons and somewhat darker appearance in this missing moon
area an easy way to distinguish between the Silvery and its closest look alike.

Starting with 2013, Crex Meadows experienced an explosion in the number of Silvery Checkerspots. In June 2014, I arrived on Crex Meadows on what appeared to be the day of an outburst of emergence of these Checkerspots. It had rained the day/evening before so there was great numbers of these checkerspots puddling on nearly every gravel road.
This picture is a small representation of the large numbers of Silvery Checkerspots on Crex Meadows that day, though it is one of the larger single groups puddling together.
Clicking the image will bring up a slightly larger view.

Colored squares along the x-axis indicate weeks none of this species were seen. Example May 1 - 15 show several visits over the years with no sightings of the Silvery Checkerspot.
