Difference between a Wasp and a Hornet
Categories of Wasps
There are three categories of wasps: parasitic wasps, which are primarily concerned with laying eggs; solitary hunting wasps, defined by their very name as baby caretakers that go out and return with paralyzed prey to feed their young; and social wasps, the annual colony-building breed that humans are most likely to encounter. This last group can be split, again, into three different tiers, and it is within these additional tiers that the hornet can be found.
Hornets Are Wasps
Hornets are most definitely a type of wasp, scientifically designated by the name Dolichovespula. The baldfaced hornet is the most common type, and amounts essentially to a big black and white wasp. They hunt other insects rather than feast on human food and garbage, as do most wasps. Hornets nests, which can be found in various wilderness and residential environments, also tend to be bigger than wasps nests.
Classification of Hornets and Wasps
The classification of hornets and wasps can get at times a little tricky. Some for example insist that the bald-faced hornet is not a hornet at all, but a wasp related more closely to the yellow jacket side of the species. There is even one species, the oriental hornet, that has been found to have solar energy storing cells built into their bodies. Scientists examining underground colonies of this hornet type discovered cuticles in their skin that absorbed 99% of the energy emitted from sunlight, explaining why they preferred also to work at the hottest point of the day: high noon. However, researchers still aren't sure exactly what the purpose of this stored energy is. Possibilities include warmth and the more sophisticated powering of enzyme-altering organic activity.
