Basis for Former Listing
Marpissa grata (a species of jumping spider) is a Great Lakes endemic known only from Michigan and Minnesota. It was originally collected by Gertsch (1936) in Minneapolis, Minnesota, and is known from five counties. This suggests that the Minnesota populations may be significant to the conservation of this species nationally. Marpissa grata was listed as a special concern species in Minnesota in 1996. Special concern jumping spiders are those known from three or more sites in Minnesota but with significant range restrictions or particular habitat associations that make their populations appear vulnerable from a conservation standpoint.
Basis for Delisting
Since its listing as a special concern species, M. grata has been documented at eight new sites in six additional counties distributed widely across the state. These data suggest that this species is more common and widely distributed in Minnesota than was formerly believed. Marpissa grata was delisted in 2013.
