European Hornet Facts
- This dazzling Arthropod most frequently goes by the informative common name of European Hornet is most of its natural range. Yet, the invertebrate does have at least a few alternate general titles. These include such terms as giant hornet or brown hornet.
- Within the scientific community, however, it’s perhaps better known by its technical designation. Thankfully, that’s an extremely simple one the average layperson to pronounce. That’s because this insect holds the official moniker of Vespa crabro.
- The marvel of Nature received that epithet due to the efforts of Carl Linnaeus. The highly esteemed Swedish zoologist accomplished the first recognition of it as a separate and distinct species. He managed that scientifically noteworthy deed in 1758.
- Until recently entomologists believed that at least one subspecies of this natural marvel existed. In-depth research, though, proved this to be an erroneous assumption. What was thought to be a subspecies turned out to be merely regional variations.
- Fortunately, the amazing European Hornet appears to be maintaining a population base that’s both stable and sufficient. That pleasant trend also seems to hold true across its native range. The IUCN therefore presently has no listing for it on the Red List.
- The impressive creature nevertheless should be considered as facing several potential threats to its continued existence, at least. Not surprisingly, most of these stem from the actions of man. They include the perils of both habitat loss and climate change.

In it, however, this physiological characteristic manifests itself in terms of size. Yet, it also does so in gender, too. That’s true since, like most bees and wasps, the creature possesses a three-caste system. Each of these castes presents different outward features.
Not surprisingly, queens attain the greatest average dimensions. These sometimes reach lengths equaling as much as 1.4 in (3.5 cm). Most, though, do not quite reach this size. She also has a greater mass than either the males or workers. Coloring is the same for all, though.
Workers, meanwhile, grow to an average length of approximately 1 in (2.5 cm). Their body shape, and likewise mass, also remains less than that of the queen. Along with her, these members of the hive additionally possess a total of size abdominal segments.

European Hornet Distribution, Habitat, and Ecology
The amazing European Hornet evolved as native to a surprisingly large expanse of the earth’s surface. The exact nature of that zone of habitation might surprise some people, however. That’s because, despite the implication of its name, it isn’t merely native to Europe.
The impressive Arthropod also developed as endemic to parts of Asia, as well. Within that greater territory, its range extends from the United Kingdom, in Europe, to as far away as Japan, in Asia. Now, though, it’s been introduced into other areas of the world.
Nature provided the marvel with an evolutionary advantage over some similar species. That’s due to the fact that it evolved a moderately flexibility regarding its choice of habitat. It therefore appears in a reasonably wide range of marginally similar ecosystems.
All of these, however, are situated with temperature climates, wherever they appear. Inside such regions, though, it inhabits many places. It often lives in such locations as grasslands and forests. It’s even adapted to living near, and sometimes even in, human homes.
Like most of its kind, the European Hornet is a eusocial animal. It constructs nests made of chewed paper. Most colonies contain between 200 – 400 workers, along with a handful of males and a single queen. Larger nest, though, may contain as many as 1,000 workers.
The inverebrate further evolved as primarily carnivorous in nature. Its typical prey consists of fairly large insects, such as mantises, dragonflies, moths, beetles, and even other wasps. Yet, the insect also consumes small amounts of fallen fruit, or other sources of sugar.
