What are wasps?

German waspUp till now, there have been over 30,000 identified species of wasps, and all of them have been categorized into two: social or solitary wasps. Most of the wasp species are solitary, and as the name suggests, they operate and live alone.

Examples of such examples include parasitic wasps that are beneficial insects and are used for agricultural pest control. Meanwhile, hunting wasps hunt insects like spiders.
Only about 1,000 species of wasps have been identified as social wasps, and these are the ones encountered by people the most. Social wasps include umbrella wasps, yellow jackets, umbrella wasps, and hornets. These tend to live in colonies and work together.

The body of a wasp is divided into three segments; lower abdomen, thorax, and the head. Paper wasps or umbrella wasps have thin bodies measuring 0.75 to 1 inch in length with black wings. Meanwhile, the color of the body ranges from reddish-brown to brown, depending on the wasp species.
Wasps are found in numerous places including suburban and urban settings, playgrounds, meadows, cemeteries, orchards, cemeteries, and woodlands. While all wasps build nests, their nesting preferences differ.

Generally, the habitat of a wasp is a paper-like nest made using wood fibers chewed into a pulp. They usually build large nests in trees and in manmade structures too like house walls, attics, porch overhangs, and decks.

Wasp vs. Hornets

Female WaspBoth hornets and wasps are from the Vespidae family. Till now, there have been more than 100,000 identified wasp species with hornet being a subspecies of wasps. However, there are few differences between them, and these are as follows:

Hornets are basically large wasps with species going up to 5.5 cm in length. Hornets can be differentiated by other wasps with their larger and rounded abdomens and wider heads.
Wasps, however, greatly vary in appearance, depending on the species. While some species have two sets of wings, some are wingless. The common appearance of all wasps is along and slender body, extremely thin waist between the abdomen and thorax, a stinger, and drooping legs during flight.


All hornets are known as social insects which means there is a hierarchy, they make a nest, and live in a colony. Meanwhile, lifecycles, nesting habits, and hierarchical structures of wasps vary across the species.

Eating habits

Adult hornets mostly eat plant matter and have a tendency for sweet items like sugary processed foods, sap, nectar, and rotten fruits. They prey on other insects too and feed them to their larvae.
Meanwhile, adult wasps are predatory, and scavengers and only survive on nectar.

Hornets make use of their stings to kill their prey and defend the nests. Hornets can sting multiple times and are more painful for humans as compared to stings of other wasp species.
In wasps, the stinger is only present on the females. Certain wasp species are considered to be the most aggressive of the stinging insects like yellow jackets.
