Identification
As a member of Leuctridae (rolled-winged stoneflies), M. infuscata likely exhibits the -diagnostic trait of wings rolled flat around the at rest, rather than folded roof-like as in most stoneflies. The specific epithet 'infuscata' (darkened) may refer to coloration, though this is not confirmed in available sources. Distinction from other Moselia and western Leuctridae would require examination of male genitalia and other fine morphological characters.
Distribution
Western North America: recorded from British Columbia, Washington, Oregon, California, and Nevada.
Ecological Role
As a (Plecoptera), M. infuscata likely functions as a - in freshwater , contributing to nutrient cycling in stream . Stonefly larvae are important prey for fish and other aquatic .
