Dolichovespula maculata is a species of wasp in the genus Dolichovespula and a member of the eusocial, cosmopolitan family Vespidae.It is taxonomically an aerial yellowjacket but is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and ...
Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. [ 8 ] [ 9 ] Individual hornets can sting repeatedly. Unlike honey bees , hornets do not die after stinging because their stingers are very finely barbed (only visible under high magnification) and can easily be ...
The Asian giant hornet is intensely predatory; it hunts medium- to large-sized insects, such as bees, [35] [89] other hornet and wasp species, beetles, hornworms, [90] and mantises. The latter are favored targets in late summer and fall. Large insects such as mantises are key protein sources to feed queen and drone larvae.
These wasps are inquilines, and rely on the workers of their host nests to rear offspring since they do not have their own worker caste. The parasite kills the foundress queen before the production of her workers is complete and takes over the nest. The lifespan of the parasite after the host queen's death is limited. [4]
The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each ...
European hornets benefit from legal protection in some countries, notably Germany, where killing a European hornet or nest has been illegal since January 1, 1987, with a fine up to €50,000. [25] However, the highest reported fine levied in Germany for killing of wasps was €45, and experts report that fines are rarely imposed. [26] [27]
Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
Oriental hornets have also been found in a few isolated locations such as Mexico and Chile due to human introduction. [5] [6] The Oriental hornet lives in seasonal colonies consisting of caste system dominated by a queen. [2] The hornet builds its nests underground and communicates using sound vibrations. [7]
