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 within 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.
Corylus avellana, the common hazel, is a species of flowering plant in the birch family Betulaceae. The shrubs usually grow 3–8 metres tall. The nut is round, in contrast to the longer filbert nut. Common hazel is native to Europe and Western Asia.
Bookworm is a general name for any insect that is said to bore through books.
The Tortricidae are a family of moths, commonly known as tortrix moths or leafroller moths, in the order Lepidoptera. This large family has over 11,000 species described, and is the sole member of the superfamily Tortricoidea, although the genus Heliocosma is sometimes placed within this superfamily. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back, producing a rather rounded profile.
The ghost moth or ghost swift is a moth of the family Hepialidae. It is common throughout Europe, except for the far south-east.
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies, and flies (Diptera). Some beetles also exhibit this behavior.
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
Dyseriocrania subpurpurella is a diurnal moth from the family Eriocraniidae, found in most of Europe. The moth was first named by the English entomologist, Adrian Hardy Haworth in 1828.
The levuana moth is an extinct species of moth in the family Zygaenidae. It is monotypic within the genus Levuana.
The common walkingstick or northern walkingstick is a species of phasmid or stick insect found across North America. The average length of this species is 75mm (3 in) for males and 95mm (3.7 in) for females.
Alsophila aescularia, the March moth, is a species of moth of the family Geometridae. It is found throughout Europe and can be a pest of fruit trees.
Cydia nigricana, the pea moth, is a moth of the family Tortricidae. It is found in 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.
The leaf blotch miner moth is a moth of the family Gracillariidae. It is found in Europe, including Turkey.
Acleris semipurpurana is a species in the moth family Tortricidae, and one of several species of moth commonly known as oak leaftier or oak leaf tier. The larvae feed on the leaves of oak trees in the Eastern United States and southeastern Canada which can be a major cause of defoliation. The loss of leaves can kill or damage the affected trees, which are chiefly in the Lobatae or red oak section of Quercus, or oaks.
Cissusa indiscreta, the indiscreet cissusa moth, is a species of moth in the family Erebidae. The species is found from British Columbia, south to California and in the south-west from Arizona to central Colorado. The habitat consists of oak woodlands and mixed hardwood forests.
Eudemis porphyrana is a moth of the family Tortricidae. It is found in most of Europe, east to the eastern part of the Palearctic realm.
Setomorpha is a monotypic moth genus in the family Tineidae described by Philipp Christoph Zeller in 1852. Its only species, Setomorpha rutella, the tropical tobacco moth, was described by the same author in the same year. It is a widely spread species that has been distributed by commerce over much of the warmer parts of Africa, Eurasia, Malaysia, Australia, many Pacific islands and North and South America.
Archips argyrospila, the fruit-tree leafroller moth, is a moth of the family Tortricidae. It is found in most of the United States and southern Canada.
Curculio occidentis, the filbert weevil, is a species of weevil in the genus Curculio. The weevils are considered a pest for many species of oak tree due to the damage they cause to acorns.
