Indicator Species  
Mottled Duskywing (Erynnis martialis)  
This small butterfly has a wingspan of 2.9-4.2cm (1 1/8-1 5/8in).  The upper side of the wings are brown with irregular dark bands that give it a mottled appearance.  The caterpillars feed almost exclusively on New Jersey tea while the adults take nectar from plants such as hoary vervain and gromwell.  It is found in savannas, open woodlands, prairie hills and open brushy fields.  This butterfly is considered very rare in Ontario.
