Ephestia elutella (Warehouse Moth, Tobacco Moth), E. kuehniella (Mill Moth), Cadra cautella (Almond Moth) and C. figulilella are cosmopolitan pests of many stored food products such as dried fruits, nuts, rice, flour etc. The larvae of these species are somewhat similar. The adults are also very similar with wing markings variable and thus not very useful in separating the species. Genitalia characters serves to confidently separate them. However adults can be narrowed into Ephestia and Cadra by hind wing veins M2 and M3 being fused for some distance in the former or separated in the latter.
Reared Cadra sp. (cf. cautella) – found and reared at Franklin.
