Summary

Rhynchophorini is a prominent tribe of true weevils within the Dryophthorinae subfamily, notable for their size and plant feeding habits, particularly associated with palms.

Physical Characteristics

Weevils of the tribe Rhynchophorini are characterized by their elongated snouts and the pygidium (VII abdominal tergite) not covered by the elytra.

Identification Tips

Look for the distinctive elongated snouts and the presence of large body sizes, particularly in species like palm weevils.

Habitat

Commonly found in tropical and subtropical regions where they inhabit or feed on various plants, particularly palms and other woody plants.

Distribution

Diet

Most species feed on plant material, especially the wood, leaves, and fruit of various plants, predominantly palms.

Life Cycle

The life cycle includes egg, larval, pupal, and adult stages; larvae often develop inside plant tissues.

Reproduction

Involves the female laying eggs in plant tissues, where larvae will feed and mature.

Predators

Natural predators include birds, other insects, and parasitic organisms.

Ecosystem Role

As herbivores, they play a significant role in plant population dynamics and nutrient cycling. Some species might act as pest species, influencing agricultural practices.

Economic Impact

Species in this tribe, especially palm weevils, are known pests in agriculture, particularly affecting palm crops, which can lead to significant economic losses.

Collecting Methods
