What is Pheromone?
A '''pheromone''' is a [[scent]] given off by some animals. The scent causes a [[social]] response in members of the same [[species]]. There are many types of pheromone, such as: *[[Sex]] pheromones (to attract a partner): e.g. butterflies and moths *[[Alarm]] pheromones (to warn the group): e.g. wasps *Food trail pheromomes (to let others know what has been found): e.g. ants *[[Territory|Territorial]] pheromones: e.g. cats and dogs *Various 'short-term' pheromones cause a rapid but brief behaviour: e.g. releasing a cluster of [[Nymph (biology)|nymphs]], or positioning the body for sex. All pheromones work by [[heredity|inherited]] [[instinct]], not by learning. They occur in most animals, but are especially obvious in [[insect]]s. {{biology-stub}} [[Category:Zoology]] [[Category:Physiology]] [[Category:Hormones]] [[Category:Endocrinology]]
