The white striping in this stage is more pronounced. Their lengths at emergence were 913 mm and their final lengths before diapausing were 1116 mm. Mitchells satyr females exhibit two behavioral stages prior to egglaying. Different shades of lime green begin to appear in longitudinal bands. Larvae accepted Carex stricta and Carex prairea during foodplant studies by Szymanski and Shuey 2002 recorded larval lengths of 1538 mm in two wild individuals. stricta. Shuey 1998 suggests minimum habitat size of ha 20 acres.

Their heads are medium to dark violet brown to black with silky sheen, and are very large and bilobate. In two study sites in Michigan during 199798, males used on average 4 of available habitat, with the exception of one site in where they occupied 15. First, the females engage in dispersal flight followed by an inspection flight. There is light to moderate grazing by livestock at these sites. The first instar larvae have pale ochre or light yellowgreen color after they first emerge.

Females used 10 at one site and 5 at the other in McAlpine, Hubbell, and Pliske, 1960 Roble et al., 2001 Szymanski and Shuey, 2002. Other potential foodplants include Their lengths at emergence were mm and their final lengths before molting were 913 mm. Roble et al., 2001McAlpine et al. They fly just below or at the level of the vegetation seeking out appropriate host plants. known habitats for Mitchells satyrs are peatlands ranging on continuum from prairiebog fens to sedge meadowswamps.

Due to their short life spans and restricted environmental conditions suitable for activity, adult Mitchells satyrs primarily confine their activities to the interface zone between open sedge meadows and dense stands of shrubs or tamarack savannah areas. There is light to moderate grazing by livestock at these sites. Legge and Rabe, 1996 McAlpine, Hubbell, and Pliske, 1960 Roble et al., 2001 US Fish and Wildlife Service, 1998Limited data suggests that Mitchells satyrs have very small home ranges of less than hectares Szymanski and Shuey 2002.

The fens are comprised of mosaic of community types. There is very limited shrub cover at the Virginia sites, primarily smooth alder Alnus serrutalata. The measurements that follow the larval descriptions are from these individuals and or not reflect the sizes found in natural settings. Other potential foodplants include In two study sites in Michigan during 199798, males used on average 4 of available habitat, with the exception of one site in where they occupied 15. In Virginia, they are found in open canopy, bulrush Scirpus spp. and sedge Carex spp. dominated, boggy seepage wetlands. Tags: fish, life, wildlife, spa, food
