Pelenomus

Pelenomus is a genus of weevils belonging to the family Curculionidae. These small beetles are primarily associated with aquatic or semi-aquatic habitats and are known to feed on various aquatic plants. Members of the Pelenomus genus are typically found in Europe and Asia, though some species have been introduced to other regions.

The weevils of this genus are characterized by their elongated snouts, which are typical of weevils, and their relatively small size. Their larvae often develop inside the stems or roots of aquatic plants, contributing to the lifecycle of these insects being intimately tied to aquatic environments.

Specific species within the Pelenomus genus may exhibit preferences for particular host plants. Identification of Pelenomus species can be complex and often requires examination of morphological characteristics, including features of the snout, legs, and genitalia. Entomologists and researchers studying aquatic ecosystems often encounter Pelenomus weevils. Their presence and feeding habits can have implications for the health and structure of aquatic plant communities.
