Beneficial insects; Insect pests. - 333 - EUROPEAN CLOVER LEAF TIER (Mirificarma formosella (Hlibner)) Economic Importance - Larvae of this gelechiid were found heavily damaging 100 acres of Ladino clover at Lincoln, Placer County, California, on April 9, 1969, by Wilson. Rose clover (Trifolium hirtum) and burclover were also damaged. Adults reared from these larvae were determined by Hodges. Larvae were also collected from clover at Pleasant Grove, Sutter County, April 15, 1969, by J. Miller. This location is few miles from Lincoln infestation.

Larvae were also collected from clover at Pleasant Grove, Sutter County, April 15, 1969, by J. Miller. This location is few miles from Lincoln infestation. Adults were collected on June 7, 1967, by J. Powell 4 miles west of Georgetown, El Dorado County. Host Plants - Trifolium repens, Ladino clover, burclover, rose clover, vetch, and native clovers in California. purple Distribution - Central and southern Europe, Asia Minor, United States: California. Syria, and North Africa. Life History - Little is available on this species in the literature. In California larvae semi-skeletonize leaves of clovers. Two leaf surfaces are folded together by light webbing, followed by discoloration and drying of foliage. Pupation occurs in the folded leaves. Description - Adult - Variegated orange-brown; about inch long. Hind wing smoky; rear margin curves sharply forward near outer tip and comes to rather sharp point (see illustration). Larva - About three-eighths inch long. Light green with black head. Anal comb distinctive - 2 central spines cross each other (see illus- tration). This can be seen with a hand lens.
