Eriocranioidea
Eriocraniidae is a family of moths restricted to the Holarctic region, with six extant genera. These small, metallic moths are usually day-flying, emerging fairly early in the northern temperate spring. They have a proboscis with which they drink water or sap. The larvae are leaf miners on Fagales, principally the trees birch (''Betula'') and oak (''Quercus''), but a few on Salicales and Rosales. Characteristics Moths in this family are diurnal, flying in the spring at dawn, and in sunshine, sometimes in swarms around host trees. They sometimes come to light and also rest on twigs and branches. By tapping branches over a beating tray, they fall and remain motionless. The moths are small with a forewing length of 4–7 mm. Forewings marking are shining pale golden or purple and often mottled. The purple moths can be difficult to tell apart with certainty and may require genitalia examination. The female moth has a piercing ovipositor and the almost colourless eggs are laid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neocrania
''Neocrania'' is a genus of moth of the family Eriocraniidae. It contains only one species, ''Neocrania bifasciata'', which is found in the Coast Ranges of southern California. The wingspan is 8–9 mm for males and 7–10 mm for females. The forewings are pale brownish fuscous with a golden iridescence. The hindwings are slightly darker than the forewings and more fuscous and sometimes with a slight purplish sheen. Adults are on wing in early June in one generation per year. The larvae feed on ''Quercus chrysolepis ''Quercus chrysolepis'', commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges.

Eriocrania
''Eriocrania'' is a Palearctic genus of moth of the family Eriocraniidae. The moths are diurnal, flying in sunshine, and the larvae are leaf miners, forming blotches in leaves. Description The moths are diurnal flying in sunshine, at dawn during March, April and May. They often fly around the host trees. On cold, sunny days they can be found on the branches, and by beating a branch over a beating tray can be seen motionless, when they fall on to the cloth. At rest the wings are held at a steep angle and are purple or golden, sometimes with net-like or mottled markings. The head has spiky scales on top. Many of the adults are difficult to tell apart and can only be identified by genitalia dissection. Eggs are laid in a leaf bud or the parenchyma of a leaf. Larvae are white or gray and mine leaves, forming large blotches with long, intertwining strands of frass, on the leaves of birches (''Betula'' species), hazel (''Corylus'' species), hornbeam (''Carpinus'' species) or oaks (''Qu ...

Eriocrania Semipurpurella
''Eriocrania semipurpurella'' (Purplish birch-miner) is a moth of the family Eriocraniidae, found from Europe to Japan and in North America. It was first described by James Francis Stephens in 1835. The species closely resembles '' Eriocrania sangii'' and the larvae of both species mine the leaves of birch. Description The wingspan is 10–16 mm. Edward Meyrick gives this description: Forewings elongate, bronzy-purple, more or less sprinkled with pale shining golden; an indistinct usually small transverse pale golden dorsal spot before tornus, sometimes almost obsolete; cilia bronzy-grey, on dorsal spot ochreous-whitish; 9 absent. Hindwings with hairscales except towards margins posteriorly, bronzy-grey, posteriorly purplish-tinged. Larva whitish; head pale ochreous-brown, mouth darker in blotch in leaves of birch. The moth flies from March to April depending on the location. The moth flies in sunshine around birch trees (''Betula'' species), sometimes in swarms in March and ...

Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Walter De Gruyter
Walter de Gruyter GmbH, known as De Gruyter (), is a German scholarly publishing house specializing in academic literature. History The roots of the company go back to 1749 when Frederick the Great granted the Königliche Realschule in Berlin the royal privilege to open a bookstore and "to publish good and useful books". In 1800, the store was taken over by Georg Reimer (1776–1842), operating as the ''Reimer'sche Buchhandlung'' from 1817, while the school’s press eventually became the ''Georg Reimer Verlag''. From 1816, Reimer used the representative Sacken'sche Palace on Berlin's Wilhelmstraße for his family and the publishing house, whereby the wings contained his print shop and press. The building became a meeting point for Berlin salon life and later served as the official residence of the president of Germany. Born in Ruhrort in 1862, Walter de Gruyter took a position with Reimer Verlag in 1894. By 1897, at the age of 35, he had become sole proprietor of the h ...

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] |
Moth Trap
Moth traps are devices used by entomologists to capture moths. Most use a light source. Pheromone traps are also used. All moth traps follow the same basic design - consisting of a mercury vapour or actinic light to attract the moths and a box in which the moths can accumulate and be examined later. The moths fly towards the light and spiral down towards the source of the light and are deflected into the box. Besides moths, several other insects will also come to light, such as scarab beetles, Ichneumonid wasps, stink bugs, stick insects, diving beetles, and water boatmen. Occasionally diurnal species such as dragonflies, yellowjacket wasps, and hover flies will also visit. The reason insects, and especially particular families of insects (e.g. moths), are attracted to light is uncertain. The most accepted theory is that moths migrate using the moon and stars as navigational aids, and that the placement of a closer-than-the-moon light causes subtended angles of light a ...
