It can also be found in North Russia, specifically in Siberia and east to Amur.
Longitarsus nigerrimus is critically endangered primarily due to habitat loss and degradation of its specialized wetland environments. The species depends on specific host plants in marshy areas that are increasingly threatened by drainage, agricultural conversion, and urban development.
Key Facts
Habitat & Distribution
The species emerge in midsummer to mate and lay eggs. After they lay their eggs they die, living their young to feed on such plants as Utricularia minor and other Utricularia species. They feed on them till adulthood, and then go to overwinter. They grow up to long, with females being the largest.
