Members of this genus are characterized by patterned or banded wings, a defining feature of the Ulidiidae family. The genus is relatively poorly documented in scientific literature, with limited -level descriptions and biological data available. Observations suggest activity in temperate regions, primarily in North America.

Identification
As a within Ulidiidae, Dyscrasis possess the -diagnostic patterned wings with dark bands or spots on a hyaline background. Specific identification to species level requires examination of genitalic structures and detailed wing pattern analysis. The genus can be distinguished from other ulidiid genera by subtle differences in wing venation and body proportions, though these characters require taxonomic knowledge.
