== Hornet vs. Wasp ==
The terms hornet and wasp are often used interchangeably, but they refer to distinct classifications of insects.<ref name="ref1" /> All hornets are a type of wasp, but not all wasps are hornets.<ref name="ref2" /> The term "wasp" describes over 100,000 species of insects in the order Hymenoptera.<ref name="ref2" /> Hornets are a specific subset of social wasps belonging to the genus *Vespa*.<ref name="ref3" /> Common wasps, such as yellow jackets and paper wasps, belong to other genera like *Vespula* and *Polistes*.<ref name="ref4" /> While they share traits like the ability to sting repeatedly, there are notable differences in their physical characteristics, behavior, and nesting habits.<ref name="ref5" />

Some insects commonly called hornets are not true hornets.<ref name="ref3" /> The bald-faced hornet (*Dolichovespula maculata*), for example, is a type of yellow jacket wasp, not a member of the *Vespa* genus.<ref name="ref3" />

=== Comparison Table ===
{| class="wikitable"
|-
! 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.<ref name="ref3" />
| 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.<ref name="ref5" /> The top margin of the head is relatively large.
| Narrower waist and body.<ref name="ref5" /> Often have bright black and yellow ring patterns.<ref name="ref1" /><ref name="ref4" />
|-
| '''Diet'''
| Primarily predators of large insects like beetles, flies, and caterpillars.<ref name="ref3" /> 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.<ref name="ref3" /> The nest has a single entrance, usually at the bottom.<ref name="ref2" />
| 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.<ref name="ref3" />
|-
| '''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.<ref name="ref2" />
|-
| '''Aggression'''
| Less aggressive than many yellow jackets unless their nest is approached.<ref name="ref3" /> Their stings are typically more painful due to higher venom potency.<ref name="ref3" />
| Aggression varies. Yellow jackets are often highly defensive and may attack with less provocation, especially when foraging near humans.

=== Ecological Role ===
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.<ref name="ref5" /> Wasps and hornets are also minor pollinators, as the adults often feed on nectar from flowers.
