Large antennae on a longhorn beetle. Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
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 ...
Two examples of near-field sound communication are bee's waggle dance and Drosophila courtship songs. [12] In fruit flies, the arista of the antennae and the third segment act as the sound receiver. [12] Vibrations of the receiver cause rotation of the third segment, which channels sound input to the mechanoreceptors of the Johnston's organ. [12]
The lenght and number of these Flagellomeres determine the lenght and size of the antennae which can vary between, but also within, different species of insects. The number and form uf these units is an important factor in determing species and sub-species. Date: July 2006: Source: Own work: Author: L. Shyamal: Permission (Reusing this file) cc ...
Brachycera antenna Planthopper nymph (immature). Antenna displaying an arista. In insect anatomy, the arista is a simple or variously modified apical or subapical bristle, arising from the third antennal segment. It is the evolutionary remains of antennal segments, and may sometimes show signs of segmentation. These segments are called aristameres.

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]
