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 ...
The antennae are of the type aristate composed of three to six segments, with the third segment larger than the others; the stylus is absent (antenna of three segments) or is composed of one to three flagellomeres (antenna of four to six segments). The mouthparts are modified for sucking and adapted for feeding on flowers.
The relatively long antennae often reach half of the front wing length. Riodinidae have an unusual variety in chromosome numbers, only some very basal groups have the number typical for butterflies (between 29 and 31) or the number characteristic of Lycaenidae (23 to 24).
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 ...
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
[3] Adelidae appear in certain plants, in which the females insert their eggs or just lay among leaf litter, and the caterpillars make a case, completing their development on the ground. [ 4 ] Fairy longhorn moths feed in sunshine on nectar from the flowers of herbaceous (woody) plants.

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.
