Lamproniadae; including Prodoxidae.

Adults diurnal; relatively long-bodied; medium built (wingspan more than 8 and less than 15 times the thoracic width); wings in repose packed with the forewings directed backwards to cover hindwings and abdomen.

Head rough (-haired). Antennae of medium length to long; extending to about 0.6–0.75 times the length of the forewing; not clubbed. Antennae of males dentate (‘unipectinate’, in Incurvaria), or simple; non-ciliate (?), or simply-ciliate. The antennal scape not forming an ‘eye cap’. Eyes glabrous. Ocelli absent. Chaetosemata absent (?). Maxillary palps well developed; 5 segmented; folded. Labial palps well developed; ascending; 3 segmented. Proboscis fully developed to absent; scaly towards the base, or not scaly.

Wingspan 7–16 mm; 12–14 times the thoracic width. Wings aculeate (strewn with minute spines). Forewings narrow; about 2.9–3.1 times as long as wide; the outer margin convexly curved; apically blunt; predominantly shining-metallic (often purplish-bronzy), or neither shining-metallic nor with shining metallic markings. Hindwings ovate-lanceolate to ovate (elongate ovate); quite markedly narrower than the forewings to markedly broader than the forewings; with a rounded apex. The fringe of the hindwings 0.6–1.5 times the width of the membrane. The upper surfaces plain; with neither discal spot nor transverse lines; hindwings with a frenulum (strong in males, represented by a more distal group of costal spines in females).

Neuration of forewings and hindwings dissimilar. Forewings 11 veined (veins 5 and 9 absent in Phylloporia), or 13 veined; with 2 anal veins. The anal veins of the forewings comprising 1b and 1c (at least in I. muscalella, as illustrated by le Cerf & Herbulot). Forewings exhibiting a tubular vein 1c (this tubular at least proximally). Vein 1b of the forewings furcate proximally. The transverse vein complete, or incomplete. Forewings with an accessory cell. Hindwings 10 veined; with 3 anal veins. The anal veins of the hindwings comprising 1a, 1b and 1c. Hindwings exhibiting vein 1a; exhibiting a tubular vein 1c. The transverse vein complete. 6 veins arising from the hindwing cell. The cell-derived hindwing veins all arising independently of one another. Vein 8 of the hindwings completely independent of the cell; not approximating to vein 7.

Tibiae of middle legs 2-spurred. Posterior tibiae 4-spurred; hairy.

Eggs, larvae and pupae. Eggs smooth or minutely pitted (?). Larval prolegs 10. Larvae case-bearing (sometimes), or not case-bearing; concealed feeders; leaf-mining, or not leaf-mining (sometimes mining in flowers or fruits).

Pupae concealed. Empty pupae protruded from place of concealment.

British representation. Genera 3; 11 species. Incurvaria masculella,, Lampronia capitella (Currant Shoot Borer), Lampronia corticella (Rasberry Moth), etc.

Classification. Microlepidoptera. Suborder Monotrysia. Superfamily Incurvarioidea.
