The family is almost entirely tropical or subtropical. Although variable in size, the adults usually have a characteristic, fine, reticulated wing pattern and distinctive resting posture, with the body raised at a steep angle and the wings expanded. They differ from pyralids by the unscaled proboscis and absence of abdominal tympanal organs.


Small to large; head smooth-scaled; ocelli usually and chaetosemata always absent; antennae simple, dentate, or pectinate; proboscis present, naked, or rarely absent; maxillary palps minute, 1- or 2-segmented; labial palps porrect or recurved, sometimes very short and only 2-segmented; epiphysis present; tibial spurs 0-2-2, 0-2-3 or 0-2-4; male hind tibiae sometimes with expandible hair-pencil; fore wing with retinaculum in male a long slender hook on Sc, without wing-locking microtrichia; chorda and M stem absent from cell, all veins often separate, CuP absent, 1A + 2A with basal fork or 2A vestigial; hind wing with 2 or 3 frenular bristles in female, all veins separate, Sc sometimes connected to Rs by R 1 and approximated to, or fused with, Rs beyond cell, M 2 arising nearer to M 3 than to M 1 , CuP vestigial, 2 anal veins; tympanal organs absent. Egg of upright type. Larva without secondary setae, prothorax with 2 L setae, prolegs short, crochets uni- or irregularly biordinal, in circle or ellipse; tunnelling in twigs and stems, sometimes producing swellings, or in shelter between green leaves. Pupa with maxillary palps and pilifers defined, without dorsal abdominal spines; in silk-lined cell.


Several of the genera occurring in Australia have a wide distribution through Asia and some occur in Africa. Aglaopus pyrrhata , one of the stout-bodied Striglininae, occurs as far south as Melbourne its larvae feed on Eucalyptus , first in a cone-shaped shelter, later in a folded leaf shelter or between joined leaves. Addaea (6 spp.) belongs to the Siculodinae, in which Sc is fused with Rs beyond the cell in the hind wing. A . subtessellata occurs in southern Qld and N.S.W.; the larvae feed gregariously between joined leaves of Mallotus philippensis . A . polyphoralis from the N.T. and Qld has larvae feeding, also gregariously, between joined leaves of Diospyros ferrea . [Whalley 1976.]
