The mortality rates at infected hibernation sites in Ontario, Quebec and New Brunswick are over 80%. Members include academics, specialists, Aboriginal people or government, & biologists. Ovulation does not occur until the spring, however, and females store the males' sperm in their uteruses through the winter. [1] Historically, it was one of the most common bat species of eastern North America. If the spread of WNS continues at the current rate, the entire Canadian population would likely be impacted within 11-22 years. In particular, Laforge and his team plan to focus on four different bat species: Little Brown Myotis, Northern Myotis, Eastern Small-footed Myotis, and Tri-colored Bats.

The Center for Biological Diversity (CBD) and Defenders of Wildlife submitted a petition on June 14, 2016, requesting that the tricolored bat be listed as endangered or threatened, and that critical habitat be designated for this species under the Endangered Species Act. The USFWS determined that the petition demonstrated that listing the species as "threatened" or "endangered" may be warranted. [9], Its species name "subflavus" means "a little less than yellow", meaning yellowish or pale yellow.

As a result of the state-endangered listing, about 30 hibernacula and 120 maternity sites known to support little brown and tri-colored bats will be added to Pennsylvania Natural Diversity Inventory. The tri-colored bat is a medium-sized bat with tri-colored pelage on its back that ranges from dark grey at the base, to yellowish in the middle, and brown at the tip.

The wing membranes are black- ish, but the face and ears have a pinkish color. Pregnant females gather in small maternal colonies typically in tree cavities or foliage where they give birth to one or two pups per summer.

Individual hairs tricolored: dark gray at the base, buffy (yellowish brown) in the middle, and brown or reddish brown at the tip. [28] Additionally, the rabies virus variants associated with these two species caused 75% of cryptic rabies deaths in the US (rabies cases where the exposure route is unclear, and no bite history exists). Fish and Wildlife Service (USFWS) issued a notice that 90-day findings have been reached in response to petitions to list five species as threatened or endangered, including the tricolored bat (Perimyotis subflavus).
