Abstract
Based on biomass, larvae of Hippodamia convergens Guerin consumed an averag e of 318 adult damson-hop aphids (Phorodon humuli (Schrank)), during their development at 20 degrees C. Female larvae of Coccinella transversoguttata Falderman ate 413 adult P. humuli and males ate 357 This difference in the consumption of prey occurred only in the fourth stadium and was reflected i n a corresponding size dimorphism between female and male larvae at pupatio n.
