Diet
Seed-feeding; develop within seeds of plants. Craponius inaequalis has been documented feeding on (Vitis spp.), with larvae developing inside grape seeds.
Host Associations
- Vitis - larval food source curculio (C. inaequalis)
Life Cycle
with , , , and stages. Larvae develop inside seeds, feeding on the seed contents. Adults emerge from seeds after larval development is complete.
Ecological Role
Seed ; reduces seed viability of plants through larval feeding.
Human Relevance
Craponius inaequalis ( curculio) is an agricultural pest of grapes, causing damage by larval feeding within developing seeds. This can reduce fruit quality and yield in vineyards.
