The Asian giant hornet (Vespa mandarinia) or northern giant hornet, [2] [3] including the color form referred to as the Japanese giant hornet, [4] [5] is the world's largest hornet. It is native to temperate and tropical East Asia , South Asia , Mainland Southeast Asia , and parts of the Russian Far East .
Due to the large size of the swarm and aggressiveness of the yellow hornet, predation against them is rare. Along with other insects in Japan and Korea, they are prey to the Asian giant hornet and nests have been known to be deserted after Asian giant hornet attacks, even though they attack in groups of only 10 to 30.
In the case of the Asian giant hornet (V. mandarinia), this is also used to mobilize many workers at once when attacking colonies of their prey, honey bees and other Vespa species. [14] Three biologically active chemicals, 2-Pentanol, Isoamyl alcohol, and 1-methylbutyl 3-methylbutanoate, have been identified for this species.
The hornets, which can be 2 inches long and were formerly called Asian giant hornets, gained attention in 2013, when they killed 42 people in China and seriously injured 1,675.
A cousin of the larger northern giant hornet, the yellow-legged hornet also preys on honeybees. Originally from southeast Asia, the yellow-legged hornet can grow nests with an average of 6,000 ...
The heaviest wasp (and heaviest hymenopteran) is probably the giant scoliid wasp Megascolia procer, it can reach a body length of over 7.7 cm (3.0 in) and have a wingspan of 11.6 cm (4.6 in). The largest known social wasps are the queens of the Asian giant hornet (Vespa mandarinia). They can have a body length exceeding 6 cm (2.4 in) and a 9.3 ...
In 2022, scientists set around 1,000 hornet traps around the state. In 2023, they found one nest, which they swiftly destroyed, containing nearly 1,500 hornets "in various stages of development".
Typical mass size for the European Hornet is 477.5 ± 59.9 mg. [14] Workers average around 25 mm (1.0 in) in length, while the larger queens can reach up to 35 mm (1.4 in). [2] This is significantly larger than most common wasps (such as Vespula vulgaris), but smaller than the Asian giant hornet. Females are typically larger than males in both ...
