(1) Energy budgets are based upon the equation: C=P+R+FU, where C=consumption, P=production, R=respiration and FU=egesta. In studies of insect energetics, where all four parameters have been measured, the completed budget rarely balances. This can often be traced to inaccuracy in the R term which, w

✦ Synopsis
In a recently published energy budget for the larvae of the leafcutter bee (Wightman and Rogers, Oecologia (Berl.) 36 (1978) 245-257) respiration as estimated by respirometry amounted to only 67% of the respiration as estimated from the difference between assimilation and production. In this note it is shown that this discrepancy seems to result from an incorrect value of the oxycalorific equivalent and that a more reasonable value makes the two estimates of respiration agree.
