Erythridula lawsoniana
(Baker, 1926)
Erythridula lawsoniana is a of leafhopper in the Cicadellidae, Typhlocybinae. The Erythridula comprises small leafhoppers often referred to as 'microleafhoppers' due to their diminutive size, typically under 5 millimeters. These insects feed on plant sap using . The species has been documented from scattered localities across eastern North America, with records from Indiana, Kansas, Maryland, New Hampshire, and Ontario.

Identification
Members of the Erythridula are extremely small leafhoppers, typically under 5 millimeters in length, with slender bodies and often strikingly colorful wing patterns featuring streaks and bands. -level identification within Erythridula requires microscopic examination of genitalic structures and other fine morphological characters. Erythridula lawsoniana is distinguished from by specific features of the male genitalia and coloration patterns, though these characters are not documented in readily accessible sources. The genus can be separated from similar microleafhopper genera such as Erythroneura by subtle differences in wing venation and body proportions.
Habitat
Found in association with woody vegetation; specific plant relationships are not documented for this . Members of the Erythridula typically inhabit deciduous forests, woodland edges, and areas with diverse shrub and tree cover.
Distribution
Documented from Indiana, Kansas, Maryland, New Hampshire, and Ontario. The scattered nature of these records suggests either a genuinely disjunct distribution or under-collection due to the ' small size and cryptic habits. The Kansas record is from Leavenworth County in the northeastern part of the state.
Seasonality
have been observed in January in Kansas, suggesting in the adult stage with activity during warm winter periods. Additional records from autumn (October-November) indicate this may be most readily encountered in late-season surveys.
Diet
Feeds on plant sap, extracted from phloem tissue using . Specific plant are not documented.
Life Cycle
with , nymph, and stages. Detailed information specific to this is not available. Typhlocybinae leafhoppers typically overwinter as eggs or adults depending on species; E. lawsoniana appears to overwinter as adults based on winter observations.
Behavior
Highly mobile and wary; individuals fly readily when disturbed, making observation and photography challenging. Like other microleafhoppers, likely spends much of its time on the undersides of leaves.
Ecological Role
Herbivore; contributes to leafhopper diversity in eastern deciduous forest . Potential prey for predatory insects, spiders, and other arthropods. May serve as for , though specific parasitoid relationships are not documented.
Human Relevance
No documented economic importance. Too small and uncommon to be a significant agricultural pest. Presence indicates healthy, -free with diverse vegetation.
Similar Taxa
