    Honey bee (Apis mellifera) is being kept in different parts in the world. There are many practices which are done on honey bee colonies by beekeepers. Such practices (e.g. requeening and migratory beekeeping) lead to differences in the characteristics of honey bee colonies in the course of time. Morphological characters of honey bees can be measured to characterize honey bee populations and to be used as an indicator for productivity of honey bee colonies. To characterize honey bee populations, the known method depends on the collection of random samples of honey bee workers from different hives and locations. However, there are different factors that can affect morphological characters. Thus, studying the stability degree of these characters is required to identify fluctuation levels within open populations of honey bees and to recommend the suitable method for its characterization. Morphological characters of 96 honey bee colonies and 1440 honey bee workers in six districts were studied for two successive years and obtained results were compared. Morphological traits of the second year were lower than the first year in most of studied characters, especially cubital index, in studied districts except for tongue length which increased in all studied districts by 0.19 to 0.69 mm. Obtained results showed that, for a fast screening for alterations happened in bee populations, it is sufficient to measure cubital index and tongue length. Also, taking the mean of morphological measurements for at least two years is considered sufficient to characterize open honey bee populations.
