After a few years of beekeeping you will learn to recognize the difference between queen cells and queen cups. There will always be queen "cups" mostly along the bottom of the frame.
These can be left alone, they are there in waiting for a quick start in case the bees need them all of a sudden.

in some other post, If it has been brought up.
Just another excuse to use my high speed internet.
