Identification
Small typical of Aphidiinae: slender body with long, multi-segmented ; reduced wing venation with characteristic closed ; petiole present between mesosoma and metasoma. -level identification requires examination of wing venation patterns, antennae segmentation, and genitalia structure. Distinguished from related aphidiine by specific combinations of morphological characters detailed in taxonomic keys for the .
Distribution
Europe: recorded from Turkey (Thrace region, Edirne province), Ukraine (Forest-Steppe and broad-leaved forest zones), Denmark, and Sweden. West Palaeartic distribution.
Host Associations
Behavior
Solitary koinobiont endoparasitoid: females lay within living , larvae develop internally consuming host tissues without immediately killing the host, occurs from mummified aphid remains.
Ecological Role
agent: regulates in natural and agricultural . Potential for programs targeting cereal aphids (Sipha spp., Rhopalosiphum spp.) and other aphid pests.
Human Relevance
