An energy budget was developed for Odontopus calceatus feeding on fresh Liriodendron tulipifera leaves. Calorific content was determined for both weevil biomass and weevil feces. Food consumption was estimated to be 97% of dry body weight per day with an egestion rate of 45%. Assimilation was 50% of both dry matter and of energy per day. Respiration of O. calceatus was 0.88 cal per milligram of dry weight per day at 27%C. Based on these data and information on field population biomass for a Liriodendron forest (1965 in East Tennessee), canopy consumption was estimated at 1.9% (17.7 Kcal/m2).
