Taste is usually located on the mouthparts of the insect but in some insects, such as bees, wasps and ants, taste organs can also be found on the antennae. Taste organs can also be found on the tarsi of moths, butterflies and flies. Olfactory sensilla enable insects to smell and are usually found in the antennae. [2]
Olfactory pathway, insects. 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. [1] Thus, it is the most important sensation for insects. [1]
In non-chewing insects, such as adult Lepidoptera, the maxillae may be drastically adapted to other functions. Unlike the mandibles, but like the labium, the maxillae bear lateral palps on their stipites. These palps serve as organs of touch and taste in feeding and in the inspection of potential foods and/or prey.
Insects taste using small hair-like structures called taste sensilla, specialized sensory organs located on various body parts such as the mouthparts, legs, and wings. These sensilla contain gustatory receptor neurons (GRNs) sensitive to a wide range of chemical stimuli. Insects respond to sugar, bitter, acid, and salt tastes.
Like other insects, flies have chemoreceptors that detect smell and taste, and mechanoreceptors that respond to touch. The third segments of the antennae and the maxillary palps bear the main olfactory receptors, while the gustatory receptors are in the labium, pharynx, feet, wing margins and female genitalia, [ 42 ] enabling flies to taste ...
Most important insect behaviors must be timed perfectly which is dependent on what they smell and when they smell it. [75] For example, smell 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 ...

Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Their sense of smell is via receptors, usually on the antennae and the mouthparts. Nearly all insects hatch from eggs. Insect growth is constrained by the inelastic exoskeleton, so development involves a series of molts. The immature stages often ...
