pincer wasps

Species Guides

Bocchus is a of pincer wasps in the Dryinidae, Bocchinae. These are characterized by their distinctive chelate (pincer-like) forelegs used to capture . The genus includes both extant and fossil species preserved in Eocene amber. Extant species are known from Europe and associated with planthopper hosts (Hemiptera: Caliscelidae).

Identification

Members of Bocchus can be distinguished from other Dryinidae by features of the chelate foreleg structure. Fossil are identified based on preserved morphological characters in amber, with a published key available for fossil species of the genus.

Habitat

Extant occur in terrestrial environments where their planthopper are found. The fossil species B. schmalhauseni is preserved in Upper Eocene Rovno amber, indicating ancient forest environments that produced resin.

Distribution

Extant recorded from Hungary, Romania, Moldova, and Turkey. Fossil species known from Upper Eocene Rovno amber deposits in the Vladimirets District, northwestern Rovno region, Ukraine.

Host Associations

Caliscelis wallengreni - Hemiptera: Caliscelidae; confirmed for B. scobiolae via rearing and

Life Cycle

larval stage documented for B. scobiolae; female, male, and larva stages have been associated using mitochondrial COI sequences.

Ecological Role

Primary of planthoppers. Serves as for hyperparasitoids: Helegonatopus rasnitzyni (Hymenoptera: Encyrtidae) has been reared from B. scobiolae.

Misconceptions

The name 'Bocchus' is shared with two kings of Mauretania in classical history, which can cause confusion in general search results unrelated to entomology.

More Details

Fossil record

The first Bocchus described from Rovno amber (B. schmalhauseni) represents the only fossil record of this from that deposit, bringing the total Dryinidae species from Rovno amber to five.

Taxonomic confirmation methods

using mitochondrial COI sequences has been used to confirm life stage associations and relationships in B. scobiolae, demonstrating the utility of molecular methods for this .
