Adelidae

Bruand, 1850

The Adelidae are a family of lepidoptera, widespread all over the world with 294 (as of 2011) species, of which about 50 are visible in Europe. Most of the species have a coloration , at least partial, metallic . Although they are mainly diurnal, some species are crespucular and have a color tending to gray.
These are small, rather primitive moths which, despite having the rib system of the rear wing reduced and clearly different from that of the anterior wing, they are distinguished from Ditrysia (which represent the largest and most evolved of the four divisions into which the infraorder Heteroneura, belonging to the order Lepidoptera, is divided), for the morphology of the female reproductive system.
