Identification

Members of Erythridula are small leafhoppers, typically under 5 mm in body length, with distinctive color patterns on the wings and body. -level identification within this requires examination of genitalic structures under magnification. E. tenebrosa is distinguished from by subtle differences in male genitalia and coloration pattern, though published diagnostic features are limited in accessible literature.

Distribution

Documented from New Hampshire and New York in the northeastern United States. The limited number of records suggests it may be uncommon, undercollected, or restricted to specific types in this region.

Seasonality

have been observed in late autumn (November), suggesting this may be among the leafhoppers that remain active into the cooler months or overwinter as adults.
