European Hornet

Natural Habitat

Found in temperate regions, especially forests, woodlands, and suburban areas. They typically build their nests in dark, sheltered locations, such as hollow trees, wall voids of buildings, or sometimes underground.

Diet & Feeding

Adult European Hornets feed on tree sap, fallen fruit, nectar, and other sugary substances. They also prey on large insects like grasshoppers, crickets, and other wasps, which they chew up and feed to their larvae.

Behavior Patterns

Hornets, especially European Hornets, are social insects living in colonies. They build large paper nests in hollow trees, wall cavities, attics, or underground. They are generally less aggressive than yellowjackets but will sting if their nest is disturbed or if they feel threatened. They are active during the day.

Risks & Benefits

Risks: Can deliver painful stings, and individuals allergic to stings are at risk of anaphylaxis. Nests near human activity can be a concern due to the potential for stings. Benefits: Their predatory behavior can help control populations of other insects that may be considered pests. They also play a minor role in pollination as they visit flowers for nectar.
