FRAME END COLOURS
How can beekeepers tell how old the queen bee in a hive is or the age of the frames in it ?
Or wondered what the coloured dot on the queen is for ?
Apiarists (beekeepers) use a five year system of colours, each year having a different colour to tell how long a frame has been in the hive, and which year the queen was hatched.
For years ending in 0 or 5 the colour is BLUE
This colour is added to the back of the queen bee so that she can be easily identified in the hive and the Apiarist can tell how old she is. We also use the same colours for the plastic ends on the frame with their purpose being to tell us how old the frame is and also to space them at the correct distance apart in the supers.
We try to replace all our brood frames at least every couple of years to prevent pests in the hive so use the coloured frame ends to help us.
