2.2.1. Balance required for weighing individual bees or larvae or body parts

A well calibrated and sufficiently sensitive analytical balance should be used, automated data transfer to computer, a standard feature, facilitate higher sampling rates. Remember, most analytical balances have a precision or readability of 0.1 mg which is sufficient for larvae and adults, but near the weight of an egg. To precisely determine the latter, we recommend measuring egg length following Henderson (1992) or use a high precision micro balance.
