An oak is a hardwood tree or shrub in the genus Quercus of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne in a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve.
Quercus rubra, the northern red oak, is an oak tree in the red oak group. It is a native of North America, in the eastern and central United States and southeast and south-central Canada. It has been introduced to small areas in Western Europe, where it can frequently be seen cultivated in gardens and parks. It prefers good soil that is slightly acidic. Often simply called red oak, northern red oak is so named to distinguish it from southern red oak (Q. falcata), also known as the Spanish oak. Northern red oak is sometimes called champion oak.
Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period.
The oak processionary (OPM) is a moth whose caterpillars can be found in oak forests, where they feed on oak leaves, causing significant damage. They travel in nose-to-tail processions, often arrow-headed, with a leader followed by rows of several caterpillars abreast. They are a human irritant because of their venomous setae, which can cause skin irritation and asthma. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Notodontinae is the nominate subfamily of the moth family Notodontidae. The Ptilodoninae are sometimes merged herein. The genus list is preliminary, as not all Notodontidae have been assigned to subfamilies yet.
Cyclophora punctaria, the maiden's blush, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The species is mainly prevalent in Central and Eastern Europe. In the north, its distribution extends to southern Fennoscandia and the British Isles, in the west via France to parts of northern Spain, in the south via Italy, the Balkan Peninsula to Asia Minor. The eastern border of the distribution is roughly the Ural. In the Caucasus area, the nominate subspecies is replaced by the subspecies C. punctaria fritzae. The range of this subspecies extends as far as Iran.Cyclophora punctaria is found mainly in wooded areas with oak scrub and oak forests. In Central Europe it rises up to 700 metres in the hills, rarely up to 1,200 metres in the Alps, and regularly rises to 1,300 metres in southern Europe.
Lasiocampa quercus, the oak eggar, is a common moth of the family Lasiocampidae found in Europe, including Britain and Ireland. It feeds on a variety of plant species, and may develop over two years in higher latitudes, where it may be known as the northern eggar. Its specific name quercus refers to the fact that its cocoon generally resembles an acorn, not that its primary food source is oak.
Drymonia dodonaea, the marbled brown, is a moth of the family Notodontidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in Europe and in the area surrounding the Caucasus.
Drymonia ruficornis, the lunar marbled brown, is a moth of the family Notodontidae. It is found in Central and Southern Europe and Anatolia.
Drymonia velitaris is a moth of the family Notodontidae first described by Johann Siegfried Hufnagel in 1766. It is found in central and southern Europe and Anatolia.
Cymatophorina is a monotypic moth genus of the family Drepanidae first described by Arnold Spuler in 1908. Its only species, Cymatophorina diluta, the oak lutestring or lesser lutestring, was described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in much of Europe, with subspecies Cymatophorina diluta hartwiegi occurring in Britain.
Polyploca ridens, the frosted green, is a moth of the family Drepanidae. It is found in southern and central Europe, England, Denmark, southern Sweden and in the east up to Russia.
Drymonia obliterata, the indistinct marbled brown, is a moth of the family Notodontidae. It is found in Central and Southern Europe, Asia Minor and Armenia.
Drymonia is a genus of moths of the family Notodontidae erected by Jacob Hübner in 1819. It consists of the following species:
Drymonia dodonides is a moth of the family Notodontidae. It is found in Japan.
Fulrada is a genus of snout moths described by Carl Heinrich in 1956.
Quercus pyrenaica, also known as Pyrenean oak, or Spanish oak is a tree native to southwestern Europe and northwestern North Africa. Despite its common name, it is rarely found in the Pyrenees Mountains and is more abundant in northern Portugal and north and northwestern Spain.
Ethmia lesliesaulae is a moth in the family Depressariidae. It is found in Costa Rica, where it has been recorded from both sides of the Cordillera Volcánica de Guanacaste al altitudes ranging from 300 to 645 meters. The habitat consists of rain forests.
Ethmia normgershenzi is a moth in the family Depressariidae. It is found in Costa Rica, where it has been recorded from the east side of the Cordillera Volcánica de Guanacaste from 400 to 660 meters. The habitat consists of rain forests.
