The number of segments in an antenna varies amongst insects, with higher flies having 3-6 segments, [21] while adult cockroaches can have over 140. [22] The general shape of the antennae is also quite variable, but the first segment (the one attached to the head) is always called the scape, and the second segment is called the pedicel.
Some moths have knobbed antennae akin to those of butterflies, such as the family Castniidae. [18] Antennae are the primary organs of olfaction (smell) in Lepidoptera. The antenna surface is covered with large numbers of olfactory scales, hairs, or pits; as many as 1,370,000 are found on the antennae of a monarch. Antennae are extremely ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
All insects have antennae, however they may be greatly reduced in the larval forms. Amongst the non-insect classes of the Hexapoda, both Collembola and Diplura have antenna, but Protura do not. [9] Antennal fibrillae play an important role in Culex pipiens mating practices. The erection of these fibrillae is considered to be the first stage in ...
Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and (at most) one pair of functional, membraneous wings, [1] which are attached to

The insect pheromone is transmitted by direct contact or via a medium such as water or air. From the receiver, for example the pheromone receptors in the antenna of a male insect, the substance is received and triggers a behavioral response. The term antenna was first used to refer to the antennae of insects and subsequently in engineering. [56]
