Insect olfaction Insect olfaction Insect olfaction refers to the function of chemical receptors that enable insects to detect and identify volatile compounds for foraging, predator avoidance, finding mating partners (via pheromones) and locating oviposition habitats. Thus, it is the most important sensation for insects. Most important insect behaviors must be timed perfectly which is dependent on what they smell and when they smell it. For example, olfaction is essential for hunting in many species of wasps, including "Polybia sericea". The two organs insects primarily use for detecting odors are the antennae and specialized mouth parts called the maxillary palps. However, a recent
Ant is used to trap their insect prey. Lemon ants make devil's gardens by killing surrounding plants with their stings and leaving a pure patch of lemon ant trees, ("Duroia hirsuta"). This modification of the forest provides the ants with more nesting sites inside the stems of the "Duroia" trees. Although some ants obtain nectar from flowers, pollination by ants is somewhat rare, one example being of the pollination of the orchid "Leporella fimbriata" which induces male "Myrmecia urens" to pseudocopulate with the flowers, transferring pollen in the process. One theory that has been proposed for the rarity of pollination is
