Erythridula rufostigmosa
(Beamer, 1930)
Erythridula rufostigmosa is a of leafhopper in the Cicadellidae, Typhlocybinae. It was described by Beamer in 1930. The Erythridula belongs to the tribe Erythroneurini, a group of small leafhoppers commonly known as 'microleafhoppers' due to their diminutive size, typically under 5 millimeters. These insects feed on plant sap using . Like other members of its genus, E. rufostigmosa is likely associated with woody or herbaceous plants, though specific host records remain poorly documented.

Identification
Distinguishable from other Erythridula by specific spot patterns and coloration details, though these require microscopic examination. The species name 'rufostigmosa' indicates reddish spotting that may separate it from . Identification to species level in Erythridula typically requires examination of male genitalia structures. Separated from other Typhlocybinae by wing venation patterns and shape. Similar to other Erythroneurini microleafhoppers in general habitus but distinguished by specific marking patterns and male genitalic characters.
Appearance
Small leafhopper, likely under 5 mm in body length based on characteristics. Members of Erythridula typically exhibit colorful markings with combinations of red, orange, yellow, or green patterns on the wings and body. The specific epithet 'rufostigmosa' suggests reddish () spots or markings (stigmosa). Typhlocybinae leafhoppers have reduced wing venation and often rounded or angular . are short and bristle-like. Wings are held roof-like over the body at rest.
Habitat
Associated with vegetation in open or semi-open where plants occur. Based on observations of related Erythridula , likely found on woody plants, shrubs, or herbaceous vegetation. Specific microhabitat preferences undocumented.
Distribution
North America. Exact range poorly documented; iNaturalist records exist from the United States. The Erythridula is primarily Nearctic in distribution.
Seasonality
likely active during warmer months, typical for temperate leafhoppers. Specific period undocumented; related observed from late spring through autumn.
Diet
Phloem sap from plants, extracted using . Specific host plant unknown.
Life Cycle
Hemimetabolous development with , nymph, and stages. Nymphs feed on plant sap and undergo multiple before reaching adulthood. Specific details of duration, stage, and number of per year undocumented for this .
Behavior
Typical leafhopper including active movement on plant surfaces, jumping when disturbed, and sap-feeding. Males likely produce substrate-borne vibrations for mate location and courtship, as documented in related Typhlocybinae. on plants possible.
Ecological Role
Herbivore feeding on plant vascular tissues. Potential prey for predatory insects, spiders, and other arthropods. May serve as for . Role in plant transmission unknown but possible given tendencies.
Human Relevance
No documented economic importance. Too poorly known to assess potential as crop pest or beneficial organism. Observations contribute to understanding of leafhopper diversity.

Taxonomic Notes
The Erythridula was established by Young and is part of the diverse leafhopper fauna of North America. -level in this group relies heavily on male genitalic characters examined under microscopy. The specific epithet 'rufostigmosa' refers to reddish spots or markings, a common naming convention in the group.
Data Deficiency
This remains poorly documented in scientific literature. iNaturalist records suggest it is encountered infrequently, with only 4 observations as of the data source date. Basic biological information including plants, seasonal , and geographic range requires further study.
