Sensitive species not a species after all – how genetics solved the Arapahoe snowfly species mystery

FS News Posted on: February 22, 2019
The Arapahoe snowfly was something of an enigma. This small stonefly, an aquatic insect important to trout and familiar to trout anglers, was thought to be rare and found only in a small area of northern Colorado. This limited presence earned it a Candidate species status under the Endangered Species Act and protections as a Sensitive Species on Forest Service lands. Researchers recently found that the Arapahoe snowfly is actually not a distinct species, but rather a hybrid of two other stonefly species, which has ramifications for its conservation.

Integrative taxonomy refutes a species hypothesis: The asymmetric hybrid origin of Arsapnia arapahoe (Plecoptera, Capniidae)

Molecular tools are commonly directed at refining taxonomies and the species that constitute their fundamental units. This has been especially insightful for groups for which species hypotheses are ambiguous and have largely been based on morphological differences between certain life stages or sexes, and has added importance when taxa are a focus of conservation efforts.
