Wasp

Wasps are insects mentioned briefly in the game, School of Dragons.

Description
Wasps are any number of species belonging to the Order Hymenoptera and Suborder Apocrita, along with ants and bees. Specifically, they are any member of Hymenoptera that is not a bee or ant, as wasps occur in many Families and Genuses that might otherwise be shared with ants or wasps.

Typically, wasps are characterized by large compound eyes, an extremely narrow "waist" connecting the thorax and abdomen, a pair of long thin wings and another shorter pair, and of course the ability to sting. Unlike bees which typically die after stinging because the poison sac comes out of their abdomens, wasps can sting many times with no ill-effect to themselves.

Depending on species, wasps may form social groups or be solitary. Also depending on species, wasps may eat nectar or other plant material, parasitize other insects, or even eat carrion and garbage.

Function
Presently there is no known usage of wasps in the How to Train Your Dragon Franchise.

However in real life, some wasps are used as non-chemical pest control for crops, as some species kill or otherwise parasitize insect pest species. Environmentally, they are important to keep other insects in check and also serve as important pollinators.

School of Dragons
Stable Quests are available to the player to send their non-active dragons on in order to earn rewards. One Stable Quest called "Pesky Pests" mentions wasps.

"Johann lost supplies when he was chased by stinging wasps. Can you send some tough skinned dragons to get them back?"
