Bocchinae is a of dryinid within the Dryinidae. Members are wasps that target leafhopper and planthopper nymphs as . The subfamily is characterized by specific morphological traits in the forewing venation and antennal structure. Bocchinae represents one of several lineages within the Dryinidae, a family known for the distinctive chelae (pincer-like forelegs) found in females of many .

Identification
Bocchinae can be distinguished from other Dryinidae (Anteoninae, Aphelopinae, Dryininae) by forewing venation patterns, specifically the arrangement of in the discoidal region and the presence or absence of certain . The subfamily is further characterized by antennal segment count and the structure of the pronotum. Identification to or requires examination of male genitalia and detailed wing venation.
Habitat
Associated with supporting their leafhopper and planthopper , including grasslands, meadows, forest edges, and agricultural fields. are often found on vegetation where hosts are present.
Distribution
Recorded from multiple continents including North America, South America, Europe, Africa, Asia, and Australia. Distribution patterns follow that of the Dryinidae, with greatest diversity in tropical and subtropical regions.
Seasonality
activity coincides with the presence of nymphs, generally spring through fall in temperate regions; year-round activity possible in tropical climates.
Host Associations
- Leafhoppers (Cicadellidae) - Females capture nymphs using chelate forelegs; larvae develop externally on
- Planthoppers (Fulgoroidea) - Some utilize planthopper nymphs as
Life Cycle
Females locate leafhopper or planthopper nymphs and grasp them with forelegs. An is deposited on the , and the larva feeds externally, eventually killing the host. The mature larva spins a cocoon, often attached to vegetation or fallen to the ground. occurs within the cocoon. Development is holometabolous with complete through egg, larva, pupa, and stages.
Behavior
Females are active hunters, searching vegetation for suitable nymphs. Upon capture, hosts are held by the chelate forelegs while are deposited. may be observed running on leaves and stems rather than flying when searching for hosts.
Ecological Role
agents of leafhopper and planthopper . These herbivorous insects can be significant agricultural pests, making dryinid important natural enemies in managed and natural .
Human Relevance
Potential value in biological pest control programs targeting leafhoppers and planthoppers in agricultural systems. Not known to sting humans.
