The green oak tortrix, Tortrix viridana, also known as the European oak leafroller and the green oak moth is a distinctive green moth whose larvae feed on tree leaves, especially oak. The head, forebody and front wings are green, the hind wings lightly greyish. The wingspan is 18-24 millimetres.

An infestation of the larvae can defoliate an oak tree. The adult female lays its eggs next to leaf buds, which the larvae consume when they emerge. As the larvae grow bigger they eat larger leaves, and then roll themselves up in a full-sized leaf to pupate.

Larvae occur from April to June; adults are on wing in June and July. [1]

The Ichneumon wasp Dirophanes invisor is a parasitoid which specializes on T. viridana.

They are commonly found in many parts of Britain. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common. [2]

<i>Quercus suber</i> Species of plant

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.

Luna moth Species of insect

The Luna moth is a Nearctic moth in the family Saturniidae, subfamily Saturniinae, a group commonly known as giant silk moths. It has lime-green colored wings and a white body. The larvae (caterpillars) are also green. Typically, it has a wingspan of roughly 114 mm (4.5 in), but can exceed 178 mm (7.0 in), making it one of the larger moths in North America. Across Canada, it has one generation per year, with the winged adults appearing in late May or early June, whereas farther south it will have two or even three generations per year, the first appearance as early as March in southern parts of the United States.

Tortricidae Family of tortrix moths

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.

Brown-tail moth Species of moth

The brown-tail moth is a moth of the family Erebidae. It is native to Europe, neighboring countries in Asia, and the north coast of Africa. Descriptions of outbreaks, i.e., large population increases of several years duration, have been reported as far back as the 1500s. The life cycle of the moth is atypical, in that it spends approximately nine months as larvae (caterpillars), leaving about one month each for pupae, imagos and eggs. Larvae (caterpillars) are covered in hairs. Two red spots on the back, toward the tail, distinguish these species from other similarly hairy moth larvae. The winged adults have white wings and a hairy white body with a tuft of brown hair at the tip of the abdomen. Females lay one egg cluster, usually on the underside of a leaf of a host plant. The species is polyphagous, meaning that it feeds on many different species of trees, including pear, apple, maple and oak.

<i>Dryocampa rubicunda</i> Species of moth

Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths. It was first described by Johan Christian Fabricius in 1793. The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.

Limacodidae Family of moths

The Limacodidae or Eucleidae are a family of moths in the superfamily Zygaenoidea or the Cossoidea; the placement is in dispute. They are often called slug moths because their caterpillars bear a distinct resemblance to slugs. They are also called cup moths because of the shape of their cocoons.

<i>Pandemis cerasana</i> Barred fruit-tree tortix moth

Pandemis cerasana, the barred fruit-tree tortrix, is a moth of the family Tortricidae.

<i>Pandemis heparana</i> Species of moth

Pandemis heparana, the dark fruit-tree tortrix or apple brown tortrix, is a moth of the family Tortricidae.

<i>Archips podana</i> Fruit tree tortrix moth

Archips podana, the large fruit-tree tortrix, is a moth of the family Tortricidae. The species was first described by Giovanni Antonio Scopoli in his 1763 Entomologia Carniolica. It is found in Europe, Asia from Anatolia to Japan and is an introduced species in North America.

<i>Archips xylosteana</i> Species of moth

Archips xylosteana, the variegated golden tortrix or brown oak tortrix, is a moth of the family Tortricidae.

<i>Epiphryne verriculata</i> Species of moth

Epiphryne verriculata, the cabbage tree moth, is a moth in the family Geometridae. It is found only in New Zealand, and only feeds on the native cabbage tree ; its wings are patterned to camouflage it against dead cabbage tree leaves.

Pheromone trap Type of insect trap that uses pheromones to lure insects

A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure, as the red rubber septa in the picture, is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them.

<i>Acleris semipurpurana</i> Species of moth

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.

<i>Archips semiferanus</i> Species of moth

Archips semiferanus is a species of moth in the family Tortricidae, and one of several species of moth commonly known as oak leafroller or oak leaf roller. The larvae feed on the leaves of oak trees in the eastern United States and southeastern Canada and are a major defoliator of oak trees, which can lead to tree mortality. In Pennsylvania in the late 1960s and early 1970s, oak leafrollers defoliated over 1,045,000 acres (423,000 ha).

Oak leafroller can refer to several species of moth that feed on leaves and roll them for nests:

<i>Clepsis consimilana</i> Species of moth

Clepsis consimilana, the privet tortrix, is a moth of the family Tortricidae.

<i>Ditula angustiorana</i> Species of moth

Ditula angustiorana, the red-barred tortrix, is a moth of the family Tortricidae found in Africa, Asia, Europe and North Africa. Other common names are the fruit-tree tortrix and the vine tortrix. The moth was first described by Adrian Hardy Haworth in 1811.

<i>Pandemis corylana</i> Species of moth

Pandemis corylana, the chequered fruit-tree tortrix, hazel tortrix moth, filbert tortricid or barred fruit tree moth, is a moth of the family Tortricidae. It is found from northern and central Europe to Siberia, Korea and Japan.

<i>Archips crataegana</i> Species of moth

Archips crataegana, the brown oak tortrix, is a moth of the family Tortricidae. It is found in most of Europe east to Japan.

<i>Quercus pyrenaica</i> Species of oak tree

Quercus pyrenaica, commonly known as Pyrenean 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.
