Did You Know…
“Uhler’s tends to flutter in a hovering fashion over some fixed point on a grassy slope, while the Chryxus flits from spot to spot, seldom flying for long at any time” (Pyle, 1981). To find females, males perch and occasionally patrol below ridge crests in bunchgrass habitat. Females lay eggs singly on grasses and sedges. Fourth-stage caterpillars hibernate, emerge in the spring to feed again, and pupate just under the soil.
