European Hornets: Facts, Behavior, and Identification

European Hornets: Facts, Behavior, and Identification

European hornets, scientifically known as Vespa crabro, are fascinating insects found primarily in Europe and parts of Asia. They are the largest hornets in Europe, measuring around 1-1.5 inches in length. Despite their intimidating size, European hornets are relatively less aggressive compared to their smaller relatives. In this article, we will delve into their facts, behavior, and identification, shedding light on these intriguing creatures.

European hornets have distinct physical characteristics that set them apart from other hornets and wasps. They have a black and yellow body, similar to other hornets, but they also exhibit brown-reddish markings on their abdomen. Their heads feature large compound eyes and strong jaws, equipped for capturing prey. One distinguishing feature is their wings, which are reddish-orange and transparent. Their thorax is predominantly black with yellow stripes. Overall, their appearance is robust and stocky, making them easily identifiable.

European hornets are social insects, living in colonies that include a queen, workers, and drones. These colonies are typically established in tree hollows, attics, or wall voids. Unlike other hornets, European hornets are also known to build exposed aerial nests, usually high in trees or bushes. These nests are made from chewed wood pulp, forming a paper-like material.

Their diet mainly consists of other insects, such as flies, caterpillars, and bees. European hornets are known to be excellent predators, capturing their prey with their powerful jaws. They also visit flowers to feed on nectar, making them important pollinators.

Contrary to popular belief, European hornets are not as aggressive as their reputation suggests. They are generally non-aggressive unless their nest or colony is threatened. If a European hornet feels threatened, it may emit a loud buzzing sound as a warning sign. However, they are less likely to sting humans compared to other hornets or wasps unless provoked or handled.
