The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. [2] Most species are characterized by antennae as long as or longer than the beetle's body.
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.
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 ...
Adult drugstore beetles are between 2.5 and 3.5 millimetres (3 ⁄ 32 and 1 ⁄ 8 in) long and have a reddish-brown colour with a cylindrical body. The beetle looks superficially similar to the cigarette beetle, another ptinid beetle regarded as a pest, but can be distinguished under magnification by the lack of serration on the antennae and the presence of clubbed segments on the last several ...
[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 ...
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.
The long antennae are banded in black and orange, and there is a pale orangish transverse band at the front of the broad plate covering the prothorax. The remaining surface is dark brown or a dull purplish-black, with small orange spots on the underside of the thorax and abdomen, and a pair of orange spots on the two rear, enlarged, flattened ...
