The Adelidae are a family of lepidoptera, widespread throughout the world with 294 (in 2011) species, of which about 50 are visible in Europe.
Most species have a color, at least partial, metallic. Although they are predominantly diurnal, some species are crespucolari
and they have a color tending to gray.
These are small primitive lepidopterans that, despite having the system of the veins of the rear wing reduced and distinctly different from that of the front wing, are distinguished
from the Ditrysia (which represent the largest and most evolved of the four divisions into which the infraorder Heteroneura is subdivided, belonging to the order Lepidoptera),
for the morphology of the female reproductive system.
