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 ...

Eriocraniidae
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] |
