Larinus Sturnus
''Larinus sturnus'' is a species of cylindrical weevils belonging to the family Curculionidae, subfamily Lixinae. Description ''Larinus sturnus'' can reach a body length of about . These rather small weevils have a black, oval shaped, punctuated body, densely covered with yellow dust, with several yellowish patches of gray setae, that appear yellowish by a yellowish secretion and adhering pollen. The pronotum is one and a half times wider than long. Its oval shaped elytra are wider than the pronotum. In front of the scutellum, there is a slight but noticeable indentation. They show the characteristic rostrum of the weevil family. It is thick, long and curved, shorter in males, relatively longer in females. Its antennae are short with conspicuous clubs. This species is rather similar and often confused with other representatives of its genus, such as ''Larinus planus'', ''Larinus jaceae'' and '' Larinus turbinatus''. However, these beetles are usually larger than the similar sp ...

Weevil
Weevils are beetles belonging to the Taxonomic rank, superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than in length, and Herbivore, herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes Bark beetle, bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the Drugstore beetle, biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored cereal, grain, as does the maize weevil (''Sitophilus zeamais'') among others. The boll weevil (''Anthonomus grandis'') attacks cotton crops; it lays its ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Centaurea Scabiosa
''Centaurea scabiosa'', or greater knapweed, is a perennial plant of the genus ''Centaurea''. It is native to Europe and bears purple flower heads. Greater knapweed is found growing in dry grasslands, hedgerows and cliffs on lime-rich soil. Upright branched stems terminate in single thistle-like flowerheads, each having an outer ring of extended, purple-pink "ragged" bracts which form a crown around the central flowers. The plant has deeply dissected leaves which form a clump at the base. This species is very valuable to bees. It is also a magnet for many species of butterfly. Among them is the marbled white. This is the only known food plant for caterpillars of the Coleophoridae case-bearer moth '' Coleophora didymella''. ''Centaurea scabiosa'' has been used in traditional herbal healing as either a vulnerary or an emollient. The plant is sometimes confused with devils-bit scabious, however the leaves on this plant are arranged alternately, whereas in devils-bit they are opp ...

Centaurea Jacea
''Centaurea jacea'', brown knapweed or brownray knapweed, is a species of herbaceous perennial plants in the genus ''Centaurea'' native to dry meadows and open woodland throughout Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia .... It grows to tall, and flowers mainly from June to September. In Britain and America, it is often found as a hybrid of black knapweed, '' Centaurea nigra''. Unlike the black knapweed, the flower heads always look as if they are rayed, forming a more open star rather than a brush-like tuft. '' Centaurea ×moncktonii'' is a fertile hybrid between black knapweed and brown knapweed.

Cirsium Palustre
''Cirsium palustre'', the marsh thistle or European swamp thistle, is a herbaceous biennial (or often perennial) flowering plant in the family Asteraceae. ''Cirsium palustre'' is a tall thistle which reaches up to in height. The strong stems have few branches and are covered in small spines. In its first year the plant grows as a dense rosette, at first with narrow, entire leaves with spiny, dark purple edges; later, larger leaves are lobed. In the subsequent years the plant grows a tall, straight stem, the tip of which branches repeatedly, bearing a candelabra of dark purple flowers, with purple-tipped bracts. In the northern hemisphere these are produced from June to September. The flowers are occasionally white, in which case the purple edges to the leaves are absent. The plant provides a great deal of nectar for pollinators. It was rated first out of the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand pr ...

Cirsium Lanceolatum
''Cirsium'' is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera ('' Carduus'', ''Silybum'' and ''Onopordum'') in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). Thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. They have erect stems and prickly leaves, with a characteristic enlarged base of the flower which is commonly spiny. The leaves are alternate, and some species can be slightly hairy. E ...
