  • INDIANA BAT Scientific Name: Myotis Sodalis Miller and Allen Other
    Common Name: INDIANA BAT Scientific Name: Myotis sodalis Miller and Allen Other Commonly Used Names: Indiana myotis, social myotis Previously Used Names: none Family: Vespertilionidae Rarity Ranks: G2/S1 State Legal Status: Endangered Federal Legal Status: Endangered Description: The dorsal hair of the Indiana bat is dark chestnut gray to pinkish gray, darker at the base, and lacks luster. Individual hairs have three bands of color. The ears and wing membranes also have a flat coloration that does not contrast with the fur. The underfur is somewhat lighter colored with a pinkish cast. The hairs on the relatively small (9 mm, inch) feet are short and inconspicuous and the calcar (a spur of cartilage arising from inner side of ankle and running along part of outer wing ) is keeled. The total length is 41 - 49 mm (1 - 1 inches), the forearm length is 35 - 41 mm (1 -1 inches), the wingspread is 24 - 27 cm (9 - 10 inches), and the weight is about 5 - 8 grams (about ¼ ounce). Similar Species: In general, the Indiana bat closely resembles the little brown bat (Mysotis lucifugus). Characters of the latter that help distinguish it are a slightly larger (10mm) foot, toe hairs that extend beyond the knuckles, a keel-less calcar, and burnished bronze hair tips. Habitat: Indiana bats gather in large groups in suitable caves to hibernate, more than 85% of the population in just nine caves in Indiana, Missouri, and Kentucky. These bats need winter caves with a stable temperature of 4 - 8°C (39 - 46°F) that contain standing water which maintains relative humidity above 74%.

  • Indiana Bat Habitat Requirements
    Section II-F Bat Habitat Conservation Priorities in Missouri Indiana Bat, Northern Long-Eared Bat, and Gray Bat NOTE: The Missouri Heritage Database, adapted for NRCS Field Office Technical Guide use, will be consulted for potential impacts to the Indiana Bat, Northern Long- Eared Bat, and Gray Bat. Please refer questions regarding these Bat Habitat Conservation Priorities to the Area Biologist. Area staff should direct questions to the State Wildlife Biologist. Indiana Bat The Indiana Bat (Myotis sodalis) is a federal and state listed endangered species. When the Natural Resources Conservation Service (NRCS) provides technical or financial assistance to landowners, habitat for this species must be considered and evaluated by NRCS staff that has completed the joint agency workshop, “U. S. Fish and Wildlife Service/NRCS Coordination for the Conservation of the Indiana Bat in Missouri.” Biology of the Indiana Bat From late fall through winter, Indiana bats in Missouri hibernate in caves in the Ozark Region. During the spring and summer, the bats utilize living, injured (e.g. split trunks and broken limbs from lightening strikes or wind), dead or dying trees for roosting throughout the state. Indiana bat roost trees tend to be greater than 9 inches (dbh) with loose or exfoliating bark. Large trees (greater than 20 inches dbh) are preferred. Most important are the structural characteristics that provide adequate space for bats to roost. Preferred roost sites are located in forest openings, at the forest edge, or where the overstory canopy allows some sunlight exposure to the roost tree which is usually within 0.6 miles of water.

  • Conservation Guidance for Indiana Bat (Myotis Sodalis)
    Conservation Guidance for Indiana Bat (Myotis sodalis). Henning, Bridget; Hinz Jr., Leon C; Kath, Joe INHS Technical Report 2017 (26) Prepared for Illinois Department of Natural Resources, State Wildlife Initiative Grants Program Issue Date: 8/30/2017 Unrestricted, for immediate release Prairie Research Institute, University of Illinois at Urbana Champaign Mark R. Ryan, Executive Director Illinois Natural History Survey Leellen Solter, Interim Director 1816 South Oak Street Champaign, IL 61820 217-333-6830 Illinois Natural History Survey has undertaken a project producing documents that provide conservation guidance for listed species in Illinois for the Illinois Department of Natural Resources. The project is titled: Conservation Guidance for Species in Greatest Need of Conservation (SGNC) T- 96-R-001. The primary purpose of guidance documents is to provide various project developers/land managers with information on the species, how their actions may impact the species, and how they can minimize/mitigate/monitor those impacts. In addition, the documents may be useful for identifying research needs to direct various funds, as a first step towards recovery planning, or for informing the general public. We intend the documents to be comprehensive and inclusive of scientific and experiential knowledge of the species and its conservation. The documents incorporate information on current conservation efforts, conservation opportunities and research needs. Interviews with stakeholders were held to identify information that should be included in conservation guidance documents. We prioritized document production for species that were frequently the subject of Incidental Take Authorizations or were consulted on in the IDNR’s EcoCat program. Initial literature reviews was conducted to produce first draft documents.

    Wyoming Species Account Little Brown Myotis Myotis lucifugus REGULATORY STATUS USFWS: Petitioned for Listing USFS R2: No special status UWFS R4: No special status Wyoming BLM: No special status State of Wyoming: Nongame Wildlife CONSERVATION RANKS USFWS: No special status WGFD: NSS3 (Bb), Tier II WYNDD: G3, S5 Wyoming Contribution: LOW IUCN: Least Concern STATUS AND RANK COMMENTS In 2011, a status review was submitted to the U.S. Fish and Wildlife Service (USFWS) suggesting that Little Brown Myotis (Myotis lucifugus) be listed as Endangered on an emergency basis because of massive population declines in the northeastern U.S. from White-nose Syndrome (WNS) 1. As of 2016, the USFWS had not yet completed this assessment or issued any decision on whether Threatened or Endangered status was warranted. NATURAL HISTORY Taxonomy: There are five recognized subspecies of Little Brown Myotis: M. l. alascensis, M. l. carissima, M. l. lucifugus, M. l. pernox, and M. l. relictus 2, 3. In Wyoming, M. l. carissima is the only known subspecies3. These sub-specific designations have been questioned as recently as 2008 because of the overlapping ranges of subspecies and evidence of subspecies-level hybridization from mitochondrial and nuclear DNA analyses 4. Description: Little Brown Myotis is, with few exceptions, identifiable in the field 5. The species is a small vespertilionid bat, but medium in size among Myotis species 5. Pelage is variable in color. Generally, the dorsal side is glossy and sooty brown to pale golden brown, while the ventral side is a lighter yellow or olive brown 3, 5, 6. In early summer, juveniles can be distinguished from adults by noticeably darker pelage and lower mass 3.

  • Myotis Sodalis) in Illinois
    Transactions of the Illinois State Academy of Science (1996), Volume 89, 3 and 4, pp. 187-196 Summer Distribution of the Federally Endangered Indiana Bat (Myotis sodalis) in Illinois James E. Gardner, Joyce E. Hofmann, and James D. Garner* Illinois Natural History Survey Champaign, IL 61820 and *Illinois Department of Natural Resources Springfield, IL 62701 Present address of JEG: Missouri Highway and Transportation Department Jefferson City, MO 65102 ABSTRACT During the summers of 1985 through 1994, mist netting was conducted at 191 sites in 71 Illinois counties to determine the summer distribution of the federally endangered Indiana bat (Myotis sodalis). A total of 115 Indiana bats was captured at 35 sites in 21 counties in the southern three-fourths of Illinois. Adult male Indiana bats were also found to be using two caves and one mine during the summer. Because one cave was located in an additional county, summer records were obtained for 22 counties. Captures of reproduc- tively active females or juveniles at 24 sites in 16 counties indicated that maternity colo- nies of this species occur throughout its range in Illinois. Recaptures of banded individu- als in the same area during different summers demonstrated that Indiana bats displayed loyalty to their summer ranges. INTRODUCTION The federally endangered Indiana bat (Myotis sodalis) is a migratory species that congre- gates in caves and abandoned mines during the winter, but is more widely dispersed during the summer (Barbour and Davis 1969). The majority of this species hibernates in a few caves and one mine in Missouri, southern Indiana, and Kentucky (Brady et al.
