Summary

Hylesinini is a tribe of crenulate bark beetles within the family Curculionidae, consisting of numerous genera and species that are important to forest ecosystems but can also be economically significant as pests.

Physical Characteristics

Crenulate bark beetles are characterized by their cylindrical body shape, often displaying a rough or granulated surface texture.

Identification Tips

Look for the distinctive crenulated texture on the exoskeleton of these beetles, along with their small size and typically elongated form.

Habitat

Hylesinini beetles typically inhabit forests and wooded areas, often found beneath the bark of trees.

Distribution

The tribe can be found across the continent, with some species like Hylastinus obscurus native to the Palearctic region.

Diet

Reproduction

Reproduction typically involves female beetles laying eggs within the bark of host trees, where larvae will subsequently develop.

Predators

Natural predators include various birds, other beetles, and predacious insects that may feed on adults or larvae.

Ecosystem Role

Hylesinini beetles play a crucial role in the decomposition of wood and recycling of nutrients in forest ecosystems.

Economic Impact

They can have significant economic impact as they are known pests of timber, causing damage to trees used in forestry and landscaping.
