Chimabachidae Overview

          This family is defined by: 1) the swollen metathoracic tibia and tarsi of the larva, unique within Gelechioidea, 2) Larval D1 setae on A9 closer to each other than the D2 setae, 3) transtilla present, 4) aedeagus free instead of being fused with surrounding diaphragma, 5) antennal pecten absent, and 6) ocellus, when present, distant from eye (Hodges, 1998).
          This subfamily includes only six species in two genera (Cheimophila, Diurnea) that occur in the Palearctic Region from Western Europe to Japan. One species, C. salicella (Hübner) has been introduced into northwestern North America (Hodges, 1998)
Larvae feed in shelters of leaves or flower buds and on flowers, fruit, and leaves of several families of dicots, including Betulaceae, Cornaceae, Salicaceae, Fagaceae, Myricaceae, and Rosaceae.
