Small Skipper
The small skipper (''Thymelicus sylvestris'') is a butterfly of the family Hesperiidae. Appearance It has a rusty orange colour to the wings, upper body and the tips of the antennae. The body is silvery white below and it has a wingspan of 25–30 mm. This butterfly is very similar in appearance to the Essex skipper (''Thymelicus lineola''). In the small skipper, the undersides of the tips of the antennae are yellow orange, whereas they are black in the Essex skipper. The black area on the lower edge of the upper wings also differs. Like the other orange grass skippers the male has a distinctive black stripe made up of scent scales. Distribution This butterfly's range includes much of Europe (east to the Urals, including Ireland, Britain and Scandinavia), north Africa and the Middle East. It is typically occurring where grass has grown tall. Life cycle and food plants Eggs are laid loosely inside grass sheaths of the caterpillars food plants from July to August. The newly ...

Nikolaus Poda Von Neuhaus
Nikolaus Poda von Neuhaus (4 October 1723 – 29 April 1798) was an Austrian entomologist. In his branch of natural history, the short name Poda refers to him. Poda was born and died in Vienna. He was the author of ''Insecta Musei Graecensis'' (1761), the first purely entomological work to follow the binomial nomenclature of Carl Linnaeus.

Timothy-grass
Timothy (''Phleum pratense'') is an abundant perennial grass native to most of Europe except for the Mediterranean region. It is also known as timothy-grass, meadow cat's-tail or common cat's tail. It is a member of the genus ''Phleum'', consisting of about 15 species of annual and perennial grasses. It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th century. Upon his recommendation it became a major source of hay and cattle fodder to British farmers in the mid-18th century. Timothy can be confused with meadow foxtail (''Alopecurus pratensis'') or purple-stem cat's-tail (''Phleum phleoides''). Description Timothy grows to tall, with leaves up to long and broad. The leaves are hairless, rolled rather than folded, and the lower sheaths turn dark brown. It has no stolons or rhizomes, and no auricles. The flowerhead is long and broad, with densely packed sp ...

Butterflies Of Asia
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it fli ...

Thymelicus
''Thymelicus'' is a Palearctic genus in the skipper butterfly family, Hesperiidae. The genus is the only member of the tribe Thymelini, but many skipper butterflies are yet to be assigned to tribes, so this might change eventually.

Knapweeds
''Centaurea'' () is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America. Common names Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed). The ''Plectocephalus'' group – possibly a distinct genus – is known as basketflowers. "Cornflower" is used for a few species, but that term more often specifically means either '' C. cyanus'' (the annual cornflower) or ''Centaurea montana'' (the perennial c ...

Thistles
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the planton the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The comparative amount of spininess varies dramatically by species. For example, ''Cirsium heterophyllum'' has minimal spininess while ''Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments have greater spininess. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', ''Cirsium'', and ''Onopordum''. However, plants outside this tribe are sometimes called thistles. Biennial thistles are particularly noteworthy for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cock's Foot
''Dactylis'' is a genus of Eurasian and North African plants in the bluegrass subfamily within the grass family. ''Dactylis'' is native to North Africa, they are found throughout the world, and are an invasive species. They are known in English as cock's-foot or cocksfoot grasses, also sometimes as orchard grasses. Taxonomy The genus has been treated as containing only a single species ''Dactylis glomerata'' by many authors, treating variation in the genus at only subspecific rank within ''D. glomerata'',Flora Europaea''Dactylis glomerata''Flora of China Town''Dactylis''/ref> but more recently, there has been a trend to accept two species,Germplasm Resources Information NetworkSpecies Records of ''Dactylis'' while some authors accept even more species in the genus, particularly island endemic species in Macaronesia.Schönfelder, P., & Ludwig, D.

Meadow Foxtail
''Alopecurus pratensis'', known as the meadow foxtail or the field meadow foxtail, is a perennial grass belonging to the grass family (Poaceae). It is native to Europe and Asia. This common plant is found on grasslands, especially on neutral soils. It is found on moist, fertile soils, but avoids waterlogged, light or dry soils. The species forms dense swards leading to low botanical diversity. This species is widely cultivated for pasture and hay, and has become naturalised in many areas outside its native range, including Australia and North America. Description It flowers from April until June – one of the earliest grasses to do so. Any survey work carried out in mid-summer may miss the grass as a result of this. It can grow to a height of about . The stem is erect and hard at the shaft, the sheathes being smooth and cylindrical. The leaves are about wide and hairless. Meadow foxtail has a cylindrical inflorescence with glumes about wide and spikelets about long. The l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Brome
''Brachypodium sylvaticum'', commonly known as false-brome, slender false brome or wood false brome, is a perennial grass native to Europe, Asia and Africa. It has a broad native range stretching from North Africa to Eurasia. The bunchgrass is most commonly found in forests and woodlands, preferring the shaded canopy, but may grow in open areas. It prefers well drained neutral and calcerous soils, and avoids wet conditions. Description ''Brachypodium sylvaticum'' is a tall tufted perennial bunchgrass that grows up to about a high. The drooping leaf blade of the plant is dark green, or bright-yellow green, flat and up to 12 mm wide with a fringe of hairs surrounding the edge of the leaf. The leaves do not have auricles. The leaf blade is joined to the hollow culm by the leaf sheath. This hairy sheath is open and surrounds the culm. The culm is pilose (long, soft, hairy), and typically has 4 to 5 nodes. The ligules are blunt, long. The grass has drooping narrow long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creeping Soft Grass
''Holcus mollis'', known as creeping soft grass or creeping velvet grass, is a species of grass, native to Europe and western Asia. Description ''Holcus mollis'' is a rhizomatous perennial grass found in woods and hedgerows, growing to tall. It has rhizomes that occur around deep in soil or sometimes deeper. Rhizome growth occurs in the period May to November but is fastest from mid-June to mid-July. The rhizomes have many dormant buds that do not develop unless the rhizomes are disturbed and then fresh aerial shoots may arise from the broken fragments. It flowers from June to July. The main distinguishing characteristics from '' H. lanatus'' are the presence of rhizomes, and the bearded nodes or 'hairy knees' on the culm. Habitat ''Holcus mollis'' is favoured by conditions in woodland clearings and at the early stages of coppicing. Growth and flowering are restricted as the tree canopy develops. It is often a relict of former woodland vegetation, surviving in open grass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
