Ants (Family Formicidae) are related to bees and wasps, and a similar body shape can be seen. Most ants however, lack wings, with only certain individuals such as a queen possessing them. Like bees, ants can have a very complex social structure as well as a very varied one, depending on the species. Some ant colonies may consist of a few dozen individuals and others can number in the thousands. Typically, but not always, there are one or a few queens or breeding females. The majority of the colonies are workers who scout for food, maintain the colony, take care of eggs, defend the nest, and find food. Some species even have distinct morphological divisions in their workers. Some ant species are even known to essentially "farm" other insects and plants and change the landscape. Ant communication is very complex and carried out through chemical secretions, pheromones, visual cues, and touch.
In the Book series, ants are mentioned as a home remedy in Old Wrinkly's Cures for Common Illnesses, a text appearing within How to Cheat a Dragon's Curse.
In reality, ants have been employed in medicine, as well as a food source for some cultures. Some ants with large mandibles have even been used as a sort of suture to close wounds. Some ant species are beneficial insects to farming, while others are considered pests. Occasionally ant colonies are kept in enclosed terrariums to observe their behaviors.
Ants appear in a text about home remedies by Old Wrinkly, but are not specifically mentioned as a remedy on the page pictured in the book.
