Chrysocharis prodice
(Walker, 1839)
Chrysocharis prodice is a minute in the , first described by Francis Walker in 1839. The Chrysocharis comprises known as parasitoids of leaf-mining , particularly (: ). This species is recorded from multiple Canadian provinces, indicating a northern distribution pattern. Like other eulophids, it likely plays a role in regulating of herbivorous insects in forest and agricultural .

Identification
Distinguished from other Chrysocharis by combination of: metallic green- coloration with coppery reflections; specific antennal proportions (exact ratios require microscopic examination); patterns with specific arrangement of on . Separation from congenerics requires examination of male and female structure. Distinguished from similar eulophid (e.g., Closterocerus, Derostenus) by structure and propodeal position.

Habitat
Associated with supporting leaf-mining . Recorded from forested and semi-open environments across Canadian provinces. Likely occurs in deciduous and mixed woodlands where leaf-miners are abundant. Specific microhabitat requirements not documented.
Distribution
Canada: Alberta, British Columbia, Manitoba, New Brunswick. Distribution records suggest transcontinental northern range, though precise southern limits unknown. Absence of records from United States may reflect limited sampling rather than true absence.
Host Associations
- Agromyzidae - probable Chrysocharis is known to parasitize leaf-miners; specific records for C. prodice not confirmed
Ecological Role
Probable of leaf-mining , contributing to natural of herbivorous in forest and potentially agricultural .
Human Relevance
Potential value in programs targeting pests, though specific applications not documented. No known negative impacts.

Taxonomic History
Originally described by Francis Walker in 1839. Walker described numerous from material in the British Museum; locality not specified in original description. Modern revision of North Chrysocharis needed to clarify species boundaries.
Identification Challenges
-level identification in Chrysocharis requires specialized taxonomic expertise and access to or authoritative revisionary works. External often insufficient for definitive identification.
