Changes
*The queen is living easily three years and is commonly kept two seasons before changing. During collecting this material the longest reported lifespan for queen has been seven years.
*The queen is very good at hiding herself on the comb by hiding under the worker bees, by hiding in the holes of the comb, and by moving side to side during the inspection.
*The queen has the same color as the worker bees, so [[Marking queen|marked queens ]] are easier to find.
*The ''A. m. mellifera'' bees are a little bigger and darker, and have longer hairs on their body. Additionally, they don´t have any yellow stripes on the abdomen.
*The queen usually goes to a newly supplied wax comb.
*The colony can be sensitive to chalk brood [[Infectious diseases and parasites | disease]] in spring and early summer. The normal temperature of sealed brood is +34℃. Disease spores are activated if the sealed brood’s temperature goes down to +27 ℃. There can be more than four pupae for one worker bee to warm up in early summer. As a result, the brood area should not be opened until the temperature is at +17℃ in order to avoid a temperature drop in the sealed brood area and thereby inducing the chalk brood disease.
*Compared to other subspecies, Nordic bees usually have fewer worker bees in [[Winter to Spring|spring]], but they still collect the same amount of honey.
