| Vespinae, with the exception of hornets, belong to the colony building Paper wasps, another category of Vespidae which are often difficult to distinguish. Vespinae are larger than the other Vespidae, the body being broader which is the decisive criterion for differentiation.

This species belongs to the family Vespidae, in the order Hymenoptera, the suborder Apocrita, the superfamily Vespoidea, the subfamily Vespinae and the genus hornets (Vespa). There are several sub-species of Vespra crabro, for example: Vespa crabro crabro, Vespa crabro germana, Vespa crabro vexator, Vespa crabro crabroniformis, Vespa crabro borealis, Vespa crabro oberthuri, Vespa crabro flavofasciata, Vespa crab... | | |
| | | Vespa crabro reproduce once a year. As a social wasp, it counts among the colony building insects. The colony has a life span of one year. The population comprises 100 to 700 (in extreme cases up to 1000) hornets. | | |

The eyes of the hornet are clearly visible and appear in the shape of a "C". The thorax and abdomen of european hornets are hairy. The upper surface of the chest (thorax) of the subspecies Vespa crabro crabro is dark coloured in the middle, while the subspecies Vespa crabro germana have a narrow red marking shaped like a "V" on their Mesoscutum. The ab... | | |

Vespa crabro are easily confused with oriental hornets (Vespa orientalis), and the female workers look very similar to the queen of the median wasp (Dolichovespula media). | | |
| | Female worker european hornets live for 3-4 weeks, drones,1-2 months, and the queen, up to 14 months. The queen, is the only member of the colony who overwinters. In the middle of April she leaves her hiding place and at the beginning of May,starts to establish a new nes... | | |
| | ...hich leads to more or less heavy fighting between individual female workers. When this happens workers may sting each other resulting in deaths. If the population of the nest expands greatly and there is no room for further development all the hornets move to a more suitable place and establish a new nest (branch formation). | | |
| | Adult european hornets’ main tasks are brood care, protection of the nest against enemies, and the hunt, both by day and night,for insects such as flies, wasps, bees, moths, grasshoppers, beetles, caterpillars or Odonata to feed the queen or the larvae. They themselve... | | |
| | Humans pose the greatest threat to the european hornet; they kill hornets out of stupidness, senselessness, superstition and quite often deliberately, and they destroy their biotopes. The bee moth (Aphomia sociella) is a parasite of the european hornet. Its larvae cover the honeycombs with webs and eat the brood bene... | | |
