It was also found in the Pacific Northwest of North America in late 2019 [6] [7] with a few more additional sightings in 2020, [8] [9] and nests found in 2021, [10] [11] prompting concern that it could become an invasive species, [12] [Ala 1] but in December 2024, it was announced that the hornets had been eradicated from the region as well as ...
[2] [3] Most species only occur in the tropics of Asia, though the European hornet (V. crabro) is widely distributed throughout Europe, Russia, North America, and north-eastern Asia. Wasps native to North America in the genus Dolichovespula are commonly referred to as hornets (e.g., baldfaced hornets), but all of them are actually yellowjackets.

A few other related genera also are sometimes referred to as "cicada killers", e.g. Liogorytes in South America and Exeirus in ...
Sphex pensylvanicus, the great black wasp, is a species of digger wasp. [3] It lives across most of North America and grows to a size of 20–35 mm (0.8–1.4 in). The larvae feed on living insects that the females paralyze and carry to the underground nest.
The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length; among the largest solitary wasps is a group of species known as tarantula hawks, along with the giant scoliid of Indonesia (Megascolia procer).
The wasp is on average 3 cm (1 in) to 5 cm (2 in) in length and is amber-yellow with yellow rings on its abdomen. Wasps in the genus Sphecius are not habitually aggressive and use their venom mainly to paralyse cicadas which they take back to their nests to feed their young. The females catch around four or more cicadas for provisioning, place ...
