Chrysocharis occidentalis

(Girault, 1916)

Chrysocharis occidentalis is a of in the Eulophidae, first described by Girault in 1916. The Chrysocharis comprises small chalcidoid wasps known for their role as agents of leaf-mining insects. Like other members of Eulophidae, this species likely develops as an internal parasitoid of larval insects, though specific associations for C. occidentalis remain poorly documented. The species has been recorded from western North America including California and Canadian provinces.

Identification

Identification of Chrysocharis occidentalis requires examination of microscopic morphological features typical of Eulophidae, including with reduced funicular segments, reduced wing venation with a single closed behind the , and a compact, often metallic body. The specific epithet 'occidentalis' refers to its western distribution. Distinguishing C. occidentalis from depends on subtle characters of the mesosoma, petiole, and genitalia that are not readily summarized from available sources.

Distribution

Recorded from California, USA; Manitoba, Canada; and New Brunswick, Canada. The specific epithet suggests a western North American distribution pattern.

Ecological Role

As a member of Eulophidae, this likely functions as a of leaf-mining insects (Lepidoptera, Diptera, Coleoptera, or Hymenoptera), contributing to natural in its . The Eulophidae is among the most important groups of parasitoids for biological control of agricultural pests.
