Neonympha mitchelli
This endangered butterfly is only found in small, isolated populations in Michigan, Indiana, Alabama, and Mississippi. In the southern portion of its range, it depends on beaver dam wetlands, a fragile and often temporary habitat, for survival. Its larvae develop on sedges on the periphery of the wetlands and the butterflies can be found with a distinctive bouncing flight just above the grasses. The Mississippi Entomological Museum houses several specimens being used in ongoing genetic and morphological research on this butterfly.
