Status Reviews for Four Midwestern Species

Sept. 18, 2015 - Positive 90-Day Findings


In response to petitions to list, reclassify and designate critical habitat for a number of species, the Service made substantial findings for 23 species and not substantial findings for 2 species. A "Substantial Finding" means that the petition provides enough information to substantiate that listing these species may be warranted.  After a substantial finding, the Service begins a thorough status review to determine whether to propose listing any of these species under the Endangered Species Act.

Our findings are in the Sept. 18, 2015, Federal Register.  Included in the 23 substantial findings are four species with ranges that extend into the Midwest.


News Release (Sept. 17, 2015)


Federal Register Notice (Sept. 18, 2015)


From petition: The northern bog lemming is found only in the northern hemisphere in subarctic climates along the northern tree line south into Washington, Idaho, Montana, Minnesota, and New England.  Though they typically inhabit sphagnum bogs, they can occasionally be found in other habitats including alpine tundra, wet subalpine meadows, and mossy forests.


  • Regal fritillary (Speyeria idalia)
    Range : AR, CO, CT, DE, IL, IN, IA, KA, ME, MD, MA, MI, MN, MO, MT, NE, NH, NJ, NY, NC, ND, OH,  OK, PA, SD,VT, VA, WV, WI
    Petition from Wild Earth Guardians

From petition: The regal fritillary’s habitat and reproductive characteristics make it particularly vulnerable to extirpation. It lives in remnant prairie habitats, has an extended reproductive diapause (extended period of time between mating and laying eggs), and deposits its eggs throughout its habitat on the ground near hostplants rather than on the hostplants.


Regal fritillary butterflies live in tall-grass prairie and other open and sunny locations such as damp meadows, marshes, wet fields, and mountain pastures.


Adults feed on nectar from various flowers such as milkweeds, thistles, red clover, and mountain mint. Violets are the sole larval foodsource.

Fact Sheet


From petition: The rusty patched bumble bee was historically common from the Upper Midwest to the eastern seaboard, but in recent years it has been lost from more than three quarters of its historic range and its relative abundance has declined by ninety-five percent.


Occasionally nests of the rusty patched bumble bee have been observed above ground. However, nests are usually one to four feet below ground in abandoned rodent nests or other cavities. This species has been observed or collected from woodlands, marshes, agricultural landscapes, and, more recently from residential parks and gardens.

Bumble Bee Watch - Bumble Bee Watch is a citizen science project to track and conserve North America’s bumble bees. The site provides useful identification information.


From petition: Wood turtles live along permanent streams during much of each year but in summer may roam widely overland and can be found in a variety of terrestrial habitats adjacent to streams, including deciduous woods, cultivated fields, and woodland bogs, marshy pastures. Use of woodland bogs and marshy fields is most common in the northern part of the range. Basking sites include emergent logs over deep stream channels, stream banks, and woodland openings with low ground cover (Ernst and Lovich 2009).


Wood turtles overwinter in bottoms or banks of streams where water flows all winter, including pools underneath a layer of ice. Underwater muskrat burrows, beaver lodges, or over-bank root systems also may be used as winter hibernation sites.


The wood turtle is found in eastern North America, from Cape Breton Island, Nova Scotia, New Brunswick, and Quebec in Canada; south to northern Virginia and Eastern Panhandle of West Virginia; west through the Great Lakes region (including southern Ontario) to eastern Minnesota, northeastern Iowa, and western Pennsylvania. It may have once occurred in northeastern Ohio. Multiple factors such as dam construction, agriculture, and urban expansion have contributed to the reduction of suitable sites across its distribution range
