![]() ![]() It has a dark band at the top of its abdomen followed by dark “teardrops”. European hornets have a darker red/brown colouring on their head and thorax. ![]() Figure 2: A specimen of Vespa crabro (aka European hornet). It is a very large wasp (2.5-3.5 centimetres), but much smaller than a northern giant hornet. This species was accidentally introduced into eastern North America more than 160 years ago and today it is common in parts of Ontario. The European hornet, Vespa crabro, is regularly mistaken for the northern giant hornet. Here are the most commonly reported species that are confused for the northern giant hornet. Some wasps can grow longer and thinner and others are large but have different and distinct features on their body. Northern giant hornets may be confused with other species of wasps and insects that are present in Ontario. Northern giant hornets are not present in Ontario, and it is unknown if they can survive Ontario winters. The abdomen has alternating yellow/orange and brown bands encircling it. Northern giant hornets have large yellow/orange heads with black eyes. Northern giant hornets may be confused with other species of wasps that occur in Ontario they can only be confirmed by an expert or specialistįigure 1: A specimen of Vespa mandarinia (northern giant hornet) that is about 4 to 5 centimetres (2 inches) long.the hornets normally build nests in the ground and typically forage within a 1 km radius, but are known to go as far as 8 km from the nest.queens can be up to 4 to 5 cm in length, with a wingspan of 4 to 7 cm.worker hornets are approximately 3.5 cm in length.they have large, thick heads and can vary in colour they can be different shades of orange, yellow and brown.Northern giant hornets are generally much larger than any other hornet and most wasps found in Ontario or North America.due to the potential threat to managed honey bees, two species of hornets native to Asia – Vespa mandarinia (northern giant hornets) and Vespa velutina (yellow-legged hornet) – are named pests in Regulation 57 under the Ontario Bees Act.several Asian hornet species are considered serious predators of honey bees, the type of bees managed by beekeepers in Canada.all the species of “true hornets” (members of the genus Vespa) are native to Eurasia and northern Africa none are native to North America.Vespa is a genus (category) of social wasps that live in large colonies composed of a queen and hundreds of workers.hornets are a type of wasp, which is a stinging insect.See the Report a sighting section of this page for more information. Identification must be confirmed by a specialist such as an entomologist or taxonomist. Northern giant hornets cannot be verified without a specimen or a photograph. These hornets are generally not interested in humans, pets or large animals, but they can aggressively attack humans or animals if they get too close to a nest or a honey bee colony that is being attacked. They can also destroy honey bee colonies in less than 24 hours. These hornets pose a serious threat to Ontario’s agriculture and native biodiversity, including resident bees and wasps. Northern giant hornets are predatory as they hunt insects for food, including honey bees. They are the largest species of hornet in the world and are native to temperate and tropical regions in China, Korea, Japan and northern India. Contact a pest control professional for infestations of yellow jackets or paper wasps.Northern giant hornets ( Vespa mandarinia) are also known as Japanese giant hornets and have been referred to as ‘murder hornets’ in the media. In the event of a severe reaction, a medical professional should be contacted. However, paper wasps can deliver painful stings when threatened, and some people experience severe allergic reactions to the venom. ![]() Most paper wasp species are also considered beneficial, as they control other pest populations and assist in pollination. Paper wasps consume primarily nectar and feed insects like caterpillars to their larvae. Paper wasps build nests that typically are smaller, under protected overhangs like door frames, and umbrellalike with the nest cells exposed. Yellow jackets are aggressive and can oftentimes be found swarming trash cans and spills of human food. Yellow jackets often build their nests in burrows in the ground or large sac-like, above-ground nests. While they appear extremely similar to yellow jackets, paper wasps are slightly larger and differ in behavior. Most paper wasps have black or dark-brown bodies with yellow markings, although there can be some variations in color. Paper wasps can be identified by their slender bodies and long legs, which hang beneath them during flight. Most paper wasp species live in the subtropics, and are named for the paperlike appearance of their nests. Of the 200 identified paper wasp species, 22 are found in North America. ![]()
