Lixus iridis is a species of weevil found in Europe. [1]

Weevil Superfamily of beetles

Weevils are a type of beetle belonging to the superfamily Curculionoidea. They are usually small, less than 6 mm (0.24 in), and herbivorous. About 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.

Description

The adults grow up to 12–17 mm long. The body is oblong and features a yellow-grey coloration. There are three faint longitudinal grey grooves on the prothorax and the abdomen. Elbowed (characteristic of true weevils) and thin antennae are placed on the upper third of the straight and cylindrical rostrum which is as long as the prothorax. Finally, they have thin legs with little thickened femurs. [2]

Prothorax

The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects, though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera), in which the pronotum is expanded to form the entire dorsal surface of the thorax, and most treehoppers, in which the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina.

Curculionidae Family of beetles

The Curculionidae are the family of the "true" weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide.

Rostrum (anatomy) anatomical feature

In anatomy, the term rostrum is used for a number of phylogenetically unrelated structures in different groups of animals.

Biology

This species lays its eggs in June.

Etymology

The name iridis, which literally means "from Iris", refers to the Iris plant.

<i>Crambe</i> genus of plants

Crambe is a genus of about 20 species of annual and perennial flowering plants in the cabbage family Brassicaceae, native to a variety of habitats in Europe, Turkey, southwest and central Asia and eastern Africa. They carry dense racemes of tiny white or yellow flowers on stems above the basal leaves.

Heterochromia iridum Disease resulting from genetics or injury causing someone to have different colored eyes

Heterochromia is a difference in coloration, usually of the iris but also of hair or skin. Heterochromia is determined by the production, delivery, and concentration of melanin. It may be inherited, or caused by genetic mosaicism, chimerism, disease, or injury. It occurs in humans and certain breeds of dogs and cats.

Caridae is a small Gondwanan family of weevils. They are considered part of the primitive weevil group, because they have straight rather than elbowed antennae. The insertion of the antennae on the rostrum cannot be seen from above. Caridae also lack spiracles on abdominal tergites 6 and 7. The prothorax lacks lateral carinae. It has been suggested that the fossil weevil Eccoptarthrus belongs in this family, which would result in a change in the family name ; this proposal has been rejected by most coleopterists (e.g.)

Belidae Family of beetles

Belidae is a family of weevils, called belids or primitive weevils because they have straight antennae, unlike the "true weevils" or Curculionidae which have elbowed antennae. They are sometimes known as "cycad weevils", but this properly refers to a few species from the genera Parallocorynus and Rhopalotria.

Rubeosis iridis, is a medical condition of the iris of the eye in which new abnormal blood vessels are found on the surface of the iris.

Attelabidae Family of beetles

The Attelabidae is a widespread family of weevils. They are among the primitive weevils, because of their straight antennae, which are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. Attelabidae and the related family Rhynchitidae are known commonly as the leaf-rolling weevils. Rhynchitidae may be treated as subfamily Rhychitinae of the Attelabidae.

<i>Iris spuria</i> species of plant

Iris spuria is a species of the genus Iris, part of a subgenus series known as Limniris and in the Series Spuriae. It is a rhizomatous perennial plant, from Europe, Asia and Africa. It has purple or lilac flowers, and slender, elongated leaves. It is widely cultivated as an ornamental plant in temperate regions and hybridized for use in the garden. It has several subspecies; Iris spuria subsp. carthaliniae B.Mathew, Iris spuria subsp. demetrii B.Mathew, Iris spuria subsp. maritima (Dykes) P.Fourn. and Iris spuria subsp. musulmanica (Fomin) Takht. It used to have 3 other subspecies, which have now been re-classified as separate species; Iris spuria subsp. halophila, Iris spuria ssp. sogdiana and Iris spuria subsp. notha . It has many common names including 'blue iris', 'spurious iris' and 'bastard iris'.
