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
Longhorn crazy ant genetic clones and her sons are the genetic clones of her mate. The male and female gene pools thus remain completely separate (assuming workers never reproduce) and this has allowed the longhorn crazy ant to become one of the most widespread invasive species in the tropics. The process is known as double cloning and was discovered by evolutionary biologist Morgan Pearcy of the Université Libre de Bruxelles. SC Longhorn crazy ant The longhorn crazy ant ("Paratrechina longicornis"), also known as "black crazy ant", is a species of small dark-coloured insect in the family Formicidae. These ants are commonly called "crazy
