Regal Fritillary (Speyeria idalia), presently listed as a Federal Species of Concern and Endangered in Wisconsin, has been found in large grassland areas with tallgrass prairie remnants or lightly grazed pasture lands containing prairie vegetation. The larval food plants are violets, primarily prairie violet (Viola pedatifida), birdsfoot violet (V. pedata), and arrowleaf violet (V.sagittata). Adults are present between late-June and early-September, peak flight is usually the first part of July.

Associated Natural Communities and Ecological Landscapes

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Issues/Threats and Conservation Actions

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
