Longhorn Beetle

Natural Habitat

Forests, woodlands, and areas with dead or dying trees. Many species are associated with specific tree types.

Diet & Feeding

Adult longhorn beetles often feed on nectar, pollen, sap, or tree bark. Their larvae (grubs) are wood-borers and feed on the wood of trees, both living and dead.

Behavior Patterns

Adults are often active during warmer months and can be found on trees, logs, or flowers. Females lay eggs in crevices of tree bark. The larvae bore into the wood, creating tunnels as they feed and develop, a process that can take several months to several years. Some species mimic wasps.

Risks & Benefits

Risks: Larvae of some species can be significant pests of timber, fruit trees, and ornamental trees, causing damage to forestry and agriculture. Benefits: They play an important role in decomposition, helping to break down dead wood and recycle nutrients in ecosystems. Some species are also important pollinators.
