The Psychidae are a, quite small, family of moths , with about 1,350 described species.
Psychidae species can be found globally. The caterpillars of this family build small enclosures where they can hide.
Psychidaes belong to the superfamily Tineoidea. The caterpillars of Psychidae build cases, with silk and environmental materials
such as sand, earth, lichens or plant materials. These cases are related to rocks, trees or hedges, when at rest or during
the pupa stage, but may be mobile and move together with the larva. The larvae of some species feed on lichen, while others
prefer green leaves. In many species, adult females lack wings and are therefore difficult to identify precisely.
The cases of Psychidae range in size from less than 1 cm to 15 cm in some tropical species. Each caterpillar makes a case
typical of his kind, making himself more useful to identify the species that the creature itself.
Adult females of many species Psychidae have only wings, legs and mouth parts rudimentary. In some species, parthenogenesis
It is known. Adult males of most species are strong fliers with well developed wings and feathery antennae but survive
only the time necessary to reproduce because of an underdeveloped mouthparts that prevents them the feeding.
