Erythroneura bistrata
McAtee, 1920
Two-banded Leafhopper
Erythroneura bistrata is a of leafhopper in the Cicadellidae, Typhlocybinae. It belongs to a containing numerous species commonly referred to as "microleafhoppers" due to their small size. Members of this genus are known for their often vivid coloration with streaks and bands across their wings. The specific epithet "bistrata" refers to the two-banded appearance. Like other Erythroneura species, it is likely associated with woody plants and may be encountered in late season when leafhoppers are abundant.

Habitat
Based on records from Maryland, Ohio, and Pennsylvania, this inhabits temperate deciduous forest regions of eastern North America. Like other Erythroneura species, it is likely associated with woody vegetation.
Distribution
Documented from Maryland, Ohio, and Pennsylvania in the eastern United States. GBIF records indicate presence in these mid-Atlantic and Midwestern states.
Seasonality
As with many Erythroneura , are likely most abundant in late summer and autumn. iNaturalist observations (420 records) suggest regular seasonal activity, though specific data for this species is not well-documented.
Diet
Feeds on plant sap, likely from woody plants typical of the . Specific host plant associations for E. bistrata are not documented in available sources.
Behavior
Like other leafhoppers in this , individuals are wary and quick to fly when approached. They are small enough to be easily overlooked but can be abundant on vegetation.
Ecological Role
As a phloem-feeding insect, contributes to nutrient cycling in plant . Serves as prey for various including spiders, lady beetles, and . May plant , though this is not documented specifically for E. bistrata.
Human Relevance
Not documented as a significant agricultural or horticultural pest. Related Erythroneura such as E. comes (eastern grape leafhopper) are vineyard pests, but E. bistrata does not appear in pest management literature.
