Abstract
Summer larvae of the eye-spotted bud moth, Spilonota ocellana (D. and S.), appeared in unequal densities on certain portions of apple trees in Door County, Wisconsin. The resulting non-random distribution introduced a bias in data obtained of the summer larvae. This phenomenon has been reported in Quebec apple orchards (LeRoux and Reimer, 1959) where densities of summer larvae were consistently greater in the upper than in the lower tree levels, and quadrant differences often occurred in the number of eggs parasitized, spring and summer larval shelters, and pupal shelters. The present study was initiated to determine the extent of the uneven distribution of summer eye-spotted bud moth larvae and nests on young, non-bearing apple trees. Summer larvae appear shortly after the first of August when eggs begin to hatch (Oatman, 1960).
