I am grafting a few queens and have an ongoing discussion with another beek. I say that larvae that is 1 day old will take the same amount of time to hatch as a larvae that is 2 days old. He maintains that the 2 day old larvae will emerge first and that we need to estimate the age of the oldest grafted larvae in order to determine when the cells need to go into mating nucs. What is the correct protocol? Also I can tell a larvae that is just hatched-it is the same size as an egg but they grow so fast can one really say that a particular larvae is 24 hours older than another if it is maybe 2X larger. In reality a 1 day old larvae is 50X larger than a 5 day old larvae so the growth rate is exponential yes?
