Summary

Dicercini is a tribe of metallic wood-boring beetles within the family Buprestidae, consisting of over 750 species worldwide, primarily in North America. They play important ecological roles in wood decomposition but can also have economic impacts through their feeding habits.

Physical Characteristics

Dicercini beetles are characterized by their metallic coloration, often exhibiting iridescent hues of green, blue, and bronze. They typically have elongated bodies with a hardened shell (elytra) and well-developed antennae.

Identification Tips

Look for the metallic sheen and elongated body shape. The antennae are often distinctive, and the species tend to have a robust form similar to other wood-boring beetles.

Habitat

Dicercini beetles are primarily found in forested areas as they are associated with wood and plant materials, where they bore and feed. They are often found in decaying logs or under bark.

Distribution

The Dicercini tribe is distributed across North America and is found worldwide except for Australasia, with a significant concentration in tropical regions.

Diet

The larvae of Dicercini beetles are wood-borers, feeding primarily on the wood of trees and shrubs. Adults may also feed on leaves, nectar, or pollen.

Life Cycle

Dicercini undergo complete metamorphosis, starting as eggs that develop into larvae (which bore into wood), pupate, and then emerge as adults.

Reproduction

Mating occurs in the spring or summer, with females laying eggs in or on the bark of host trees. The larvae develop inside the wood, which necessitates proper host availability for successful reproduction.

Predators

Birds and other insectivorous animals are common predators of Dicercini adults and larvae, while parasitic wasps may target eggs or larvae.

Ecosystem Role

As wood-boring beetles, Dicercini play a significant role in the decomposition of dead wood, aiding in nutrient cycling and habitat creation for other organisms.

Economic Impact

Due to their wood-boring habits, some species can have economic impacts in forestry and agriculture by damaging timber and ornamental trees.

Collecting Methods

• Hand collecting from host plants
• Traps baited with pheromones
• Light traps

Preservation Methods

• Pinned specimens
• Ethanol preservation
• Collection in kill jars

Evolution

The Dicercini tribe is a relatively ancient group within the Buprestidae family, showcasing a diversity of adaptations in response to various ecological niches.

Similar Taxa

• Buprestidae
• Polybothris
• Lampetis

Misconceptions

Some may confuse Dicercini with other beetles due to their metallic appearance and wood-boring habits. They are not harmful to humans and do not bite.
