Range Description

Endemic to the United States. Known from 54 counties in eight states. There are at least 20 occurrences in Rhode Island (Carpenter pers. comm. 2000); two to three sites in Connecticut (L. Ruth pers. comm. 2001); and based on 1999 surveys there are predicted to be 30 to 50 occurrences in Wisconsin alone (Vogt pers. comm. 2000). Ward and de Maynadier (2005) list eight populations in 13 sites in Maine. Vogt (1999) recommends continued inventory the Glacial Lake Wisconsin region, as well as other areas with suitable habitat in Wisconsin. An inventory is needed in eastern Connecticut and Bristol County Massachusetts. There are several unsurveyed sites in southeastern New Hampshire as well as Atlantic white cedar swamps. In New York the Hudson Highlands and Albany pine bush should be searched (these are close to recent New Jersey record). Further early-season searches are also required.
