• Isoperla lata

  Dark Stripetail

  Isoperla lata, commonly known as the dark stripetail, is a green-winged stonefly in the family Perlodidae. It is native to North America with documented populations in Labrador, Maine, Massachusetts, Michigan, and Minnesota. The species inhabits cold-water trout streams where it functions as a predator on other aquatic insects. Research from Wisconsin indicates a slow univoltine life cycle with synchronous spring emergence and temperature-dependent egg development.
