This is a good example to see what young bee larvae looks like in the comb. You see some eggs and the larvae which are probably 2-3 days old. You will notice a white liquid inside the cells, that is royal jelly. Worker bee larvae are fed royal jelly for the first 3 days, after that they are fed nectar, honey and pollen. Only larvae that have been selected to become queens will be fed royal jelly the entire time of their development.

More young larvae feeding on royal jelly. Here you can see some that are smaller than others, just different age larvae.
