Ichneutinae
Genus Guides
4The Ichneutinae are a of braconid comprising small to medium-sized non-cyclostome . They are solitary koinobiont parasitoids that oviposit into but complete their development after the host has reached the larval stage. The subfamily has a distribution and is divided into three tribes with distinct host associations.

Identification
Distinguished from other braconid by the combination of non-cyclostome mouthparts and the absence of an occipital carina. Separation from other non-cyclostome braconids requires examination of additional morphological characters not specified in available sources.
Appearance
Small to medium-sized braconid wasps with non-cyclostome mouthpart structure. They lack an occipital carina, a ridge on the margin of the that is present in many other braconids.
Distribution
; found on all major landmasses.
Host Associations
- Sawfly larvae (Argidae, Tenthredinidae) - koinobiont Attacked by tribes Ichneutini and Proteropini
- Lepidopteran leaf-miners - koinobiont Targeted by tribe Muesebeckiini
Life Cycle
Solitary koinobiont development: are deposited into eggs, but larval development and occur after the host has developed into a larva.
Behavior
Oviposition into with delayed development until host larval stage.
Ecological Role
agents of and lepidopteran leaf-miner .
Human Relevance
Potential value in programs targeting pests and leaf-mining Lepidoptera.
