The worker longhorn crazy ant is about 2.3 to 3.0 mm (0.09 to 0.12 in) long with a brownish-black head, thorax, petiole, and gaster, often with a faint blue iridescence. The body has a few short, whitish bristles and the antennae and limbs are pale brown.
[3] Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the ...
Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched) antenna-like structures, followed by one or more pairs of biramous (having two major branches) leg-like structures, as seen in some modern crustaceans and fossil ...
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 sensitive; the feathered antennae of male moths from the Saturniidae, Lasiocampidae, and many other families are so sensitive that they can detect the pheromones of female ...
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 ...
The members of the Cerambycidae (Longhorn Beetles) family are named for their long antennae, sometimes exceedingly so. The antennae of males are usually longer than those of females, and often the antennae are attached to the head in a strange notch at the front of the eye. Styloxus fulleri is a smaller species, at about 12–13 mm in length.
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 Nematocera (the name meaning "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae.This group is paraphyletic and contains all flies except for species from suborder Brachycera [4] (the name meaning "short-horns"), which includes more commonly known species such as the housefly or the common fruit fly.
