Differences between Hornet and Wasp
Hornet vs. Wasp[edit]
The terms hornet and wasp are often used interchangeably, but they refer to distinct classifications of insects.[1] All hornets are a type of wasp, but not all wasps are hornets.[2] The term "wasp" describes over 100,000 species of insects in the order Hymenoptera.[2] Hornets are a specific subset of social wasps belonging to the genus *Vespa*.[3] Common wasps, such as yellow jackets and paper wasps, belong to other genera like *Vespula* and *Polistes*.[4] While they share traits like the ability to sting repeatedly, there are notable differences in their physical characteristics, behavior, and nesting habits.[5]
Some insects commonly called hornets are not true hornets.[3] The bald-faced hornet (*Dolichovespula maculata*), for example, is a type of yellow jacket wasp, not a member of the *Vespa* genus.[3]
Comparison Table[edit]
| Category | Hornet (*Vespa* genus) | Wasp (other social wasps, e.g., *Vespula*) |
|---|---|---|
| Size | Generally larger and more robust, from 1 to 2 inches (2.5 to 5.5 cm) in length.[3] | Typically smaller, around 0.5 to 1 inch (1.3 to 2.5 cm) long, with a more slender body. |
| Appearance | Wider head, often with reddish-brown or black and white markings.[5] The top margin of the head is relatively large. | Narrower waist and body.[5] Often have bright black and yellow ring patterns.[1][4] |
| Diet | Primarily predators of large insects like beetles, flies, and caterpillars.[3] They rarely scavenge for human food. | Omnivorous predators and scavengers. They prey on smaller insects but are also highly attracted to sugary foods, fruits, and human garbage. |
| Nesting Habits | Build large, enclosed paper nests resembling a teardrop or ball, often located high in trees, shrubs, or attics.[3] The nest has a single entrance, usually at the bottom.[2] | Nest construction varies. Yellow jackets often build nests underground or in wall voids, while paper wasps build smaller, open-comb, umbrella-shaped nests under eaves.[3] |
| Colony Size | Colonies can contain between 100 and 700 workers on average. | Varies by species. Yellow jacket colonies can be much larger, with several hundred to thousands of workers.[2] |
| Aggression | Less aggressive than many yellow jackets unless their nest is approached.[3] Their stings are typically more painful due to higher venom potency.[3] | Aggression varies. Yellow jackets are often highly defensive and may attack with less provocation, especially when foraging near humans. |
Ecological Role[edit]
Both hornets and wasps contribute to their ecosystems as predators. They help control populations of various insects and spiders, including many considered to be garden or agricultural pests.[5] Wasps and hornets are also minor pollinators, as the adults often feed on nectar from flowers.
