Blastothrix longipennis
Howard, 1881
Blastothrix longipennis is a of in the Encyrtidae, first described by Howard in 1881. It belongs to a of encyrtid wasps known primarily as parasitoids of scale insects (Coccoidea). The species has been documented in museum collections across multiple continents, including North America, Europe, and Asia.

Identification
Within the Blastothrix, B. longipennis can be distinguished by its notably long wings relative to body size, as indicated by the epithet 'longipennis' (long-winged). Species-level identification in this genus typically requires examination of antennal structure, wing venation patterns, and male genitalia. Distinguishing B. longipennis from congenerics such as B. sericea and B. erythrostetha requires taxonomic knowledge and reference to .
Distribution
Documented distribution includes: British Columbia (Canada), California and District of Columbia (USA), England (United Kingdom), and East Kazakhstan. The disjunct records suggest either a broad natural range or human-mediated , though the sparse occurrence data preclude definitive conclusions about native versus introduced status in all regions.
Host Associations
- Coccoidea - Blastothrix is primarily associated with scale insects, though specific records for B. longipennis are not documented in available sources
Ecological Role
As a member of Encyrtidae, this likely functions as a of scale insects, potentially contributing to natural of these herbivorous pests. The Encyrtidae is among the most important parasitoid groups for biocontrol of Coccoidea in agricultural and natural .
Human Relevance
Specimens of B. longipennis are present in the University of California Riverside Encyrtidae collection, one of the world's largest holdings of this . The has been preserved as both pinned specimens and microscope slides, indicating its significance for taxonomic and potentially biocontrol research. No specific applied biocontrol programs utilizing this species have been documented in available sources.
Similar Taxa
- Blastothrix sericeaCongeneric with overlapping distribution; both have been collected in California and are preserved in the UCR Encyrtidae collection. Separation requires detailed morphological examination.
- Blastothrix erythrostethaAnother congeneric with similar body plan and likely insect ; distinguished by coloration and wing characteristics.
- Blastothrix hungaricaEuropean congeneric ; B. longipennis shares the long-winged condition with this species, requiring careful comparison of for definitive identification.
More Details
Nomenclatural note
The was described by L.O. Howard in 1881. The UCR Encyrtidae collection holds both pinned and slide-mounted specimens identified as B. longipennis, indicating stable taxonomic recognition over more than a century.
Collection significance
Presence in the UCR Encyrtidae collection—started by P.H. Timberlake and curated by S. Triapitsyn—suggests this has been subject to modern taxonomic scrutiny, though published species-level treatments remain sparse.
