Schemata are interrelated and multiple conflicting schemata can be applied to the same information. Schemata are generally thought to have a level of activation, which can spread among related schemata. Which schema is selected can depend on factors such as current activation, accessibility, and priming.
Hornets will look for a sheltered location to make their nest, and such nests can be found under leaves, in tree branches, on windows, in attics, under rafters, inside abandoned buildings or vehicles, etc. Any space that is protected from the weather and undisturbed can attract hornets to nest.
Hornets are wasps of the genus Vespa, closely related to (and resembling) yellowjackets. There are about 20 hornet species. Most live in tropical Asia, but the insects are also found in Europe, Africa, and North America, where the European hornet was introduced by humans. These social insects construct hives by chewing wood into a papery construction pulp.
