Rhopalomyia grossulariae
Felt, 1911
Gooseberry Gall Midge
Rhopalomyia grossulariae, commonly known as the gooseberry , is a gall-inducing fly in the Cecidomyiidae. The was described by Felt in 1911 and is associated with gooseberry plants (Ribes spp.). Like other members of its , it induces gall formation on plants. The species has been recorded in parts of Europe, with confirmed presence in Great Britain.

Identification
Distinguished from other Rhopalomyia by its association with gooseberry (Ribes grossularia and related Ribes species). The is small and delicate, typical of Cecidomyiidae, with reduced wing venation. Specific morphological diagnostic features for field identification are not well documented in available sources. Gall on plants may aid identification.
Habitat
Associated with gooseberry and wild Ribes stands. Occurs in gardens, orchards, hedgerows, and woodland edges where plants grow.
Distribution
Recorded from Great Britain (common), with doubtful records from Belgium, France, and The Netherlands. The appears to be European in distribution.
Diet
Larvae feed internally within plant tissue, inducing gall formation on gooseberry plants (Ribes spp.).
Host Associations
- Ribes grossularia - gooseberry; primary plant for gall induction
- Ribes spp. - other currant and gooseberry
Life Cycle
Has been observed to undergo complete with , larval, pupal, and stages. Larvae develop within galls on plants. Specific timing of and stage are not well documented.
Behavior
are known to induce gall formation on plants through oviposition and larval development. Otherwise typical of gall midges in being small, weak fliers with short adult lifespans.
Ecological Role
Acts as a gall inducer on Ribes , creating plant structures that provide shelter and food for developing larvae. The ecological impact on plant has not been quantified.
Human Relevance
Considered a pest of gooseberry in areas where it occurs. Gall formation can damage developing shoots and reduce fruit production. Management in commercial and home gardens may be warranted.
