20-10-2021 RHODES, GREECE - ORIENTAL HORNET (Vespa orientalis)


The Oriental hornet (Vespa orientalis) is a social insect species of the family Vespidae. It can be found in Southwest Asia, Northeast Africa, the island of Madagascar (but no reports have been made of its presence on the island for many years), the Middle East, Central Asia, and parts of Southern Europe. Oriental hornets have also been found in a few isolated locations such as Mexico and Chile due to human introduction. The Oriental hornet lives in seasonal colonies consisting of caste system dominated by a queen. The hornet builds its nests underground and communicates using sound vibrations. The hornet has a yellow stripe on its cuticle (exoskeleton), which can absorb sunlight to generate a small electrical potential, and this might help supply energy for digging. The adult hornet eats nectar and fruits and scavenges for insects and animal proteins to feed to its young. Because they are scavengers, the hornets may also serve as a transmitter of disease following consumption of infected plants. The hornets are a primary pest to honey bees, attacking bee colonies to obtain honey and animal proteins. The sting of an Oriental hornet can be quite painful to humans and some humans are allergic to stings.


Oriental hornets can be found in Central Asia, southwestern Asia from Armenia and Turkey to India and Nepal, throughout the Middle East, in Northeast Africa, in some Afrotropical countries such as Ethiopia and Somalia, and in parts of Southern Europe: Croatia, Bosnia, Montenegro, North Macedonia, Albania, Greece, Spain, Bulgaria, Cyprus, Malta, Sicily, Sardinia and the southern half of peninsular Italy. Oriental hornets have been introduced by humans into additional locations, including Chile, Madagascar, Mexico, and Xinjiang, China, as well as the occasional introduction via fruit into Belgium and the United Kingdom.The Oriental hornet is the only member of the genus Vespa that can be found in desert climates such as those in North Africa, the Middle East, and parts of southwestern Asia.
