A small family found worldwide. Six species have been recorded in the British Isles, of which four are resident, one is an immigrant that sometimes breeds, and one has been recorded as a probable immigrant. All are small, whitish or grey moths with rather rounded forewings with basal and central scale tufts (easily lost), and could well be mistaken for micro-moths. They are not often seen by day, but come to light and sometimes to sugar. The larvae feed on woody plants, and are quite hairy. They pupate above ground in tough, sometimes boat-shaped cocoons, usually formed on a stem of the foodplants, incorporating fragments of bark.
