Essex Skipper
__NOTOC__ ''Thymelicus lineola'', known in Europe as the Essex skipper and in North America as the European skipper, is a species of butterfly in the family Hesperiidae. With a wingspan of 2.5 to 2.9 cm, it is very similar in appearance to the small skipper, ''Thymelicus sylvestris''. They can be told apart by the forward-facing flattish part of the antenna tip: in the Essex Skipper this face is black, whereas in the Small Skipper it is orange or brown. In males, there is a difference in the scent mark. In Essex Skipper this is a fine, straight, short dark line on the forewing, parallel to the wing edge; in the Small Skipper males, this line is bolder and bent. This butterfly occurs throughout much of the Palaearctic region. Its range is from southern Scandinavia through Europe to North Africa and east to Central Asia. It was only identified in the UK in 1889, and its range is expanding both in England and in northern Europe. In North America, this butterfly was accidentally ...

Ochsenheimer
Ferdinand Ochsenheimer (17 March 1767 – 2 November 1822) was a German actor and entomologist (lepidopterist). Life Ochsenheimer was born and brought up in Mainz (then in the Electorate of Mainz) and began to show an interest in butterflies and moths in his early youth. At the age of twelve he was apprenticed with a saddler but when his intellectual abilities were recognized friends of his father's enabled him to study natural history at the university. On 16 September 1788 he received his degree of ''Doktor der Philosophie''. He found employment as an educator with Stadtkommandant von Dallwigh in Mannheim, then with Baron von Reipelt. In Mannheim Ochsenheimer wrote his first stage comedies (''Er soll sich schlagen'', ''Der Brautschatz''). At the age of 27 he decided to follow a career as an actor and entered into Quandt's troupe of actors in Bayreuth. His first appearance was on 12 November 1794 as Flickwort in Gotter's ''Schwarzer Mann''. After trying his hand in several fi ...

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.

Butterflies Of Europe
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 ...

List Of Butterflies Of Great Britain
This is a list of butterflies of Great Britain, including extinct, naturalised species and those of dubious origin. The list comprises butterfly species listed in ''The Moths and Butterflies of Great Britain and Ireland'' by Emmet ''et al.'' and ''Britain's Butterflies'' by Tomlinson and Still. A study by NERC in 2004 found there has been a species decline of 71% of butterfly species between 1983 and 2003. The 2007 UK Biodiversity Action Plan (BAP) listed 22 butterfly species. The 2011 Red List of British butterflies lists 4 species as "regionally extinct" (RE), 2 as "critically endangered", 8 as "endangered (E), 9 as "vulnerable" (V), 11 as "near threatened" (NT) and 28 as "least concern" (LC) in a UK context.

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tor-grass
''Brachypodium pinnatum'', the heath false brome or tor-grass, is a species of grass with a widespread distribution in temperate regions of the Northern Hemisphere. It typically grows in calcareous grassland, and reaches tall. The flowerhead is open, with 10 to 15 erect spikelets. Distribution The plant can be found in such US states as California, Massachusetts, and Oregon. Ecology The caterpillars of some Lepidoptera use it as a food plant, e.g. the Essex skipper (''Thymelicus lineola''). It is also one of the most important host grasses for Auchenorrhyncha in central Europe.Nickel, H. (2003).

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] |
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] |
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 ...
