Honey bee life cycle lay fertilized or unfertilized eggs. Each unfertilized egg contains a unique combination of 50% of the queen's genes and develops into a haploid drone. The fertilized eggs develop into either diploid workers or virgin queens if fed royal jelly. The average lifespan of a queen is three to four years; drones usually die upon mating or are expelled from the hive before the winter; and workers may live for a few weeks in the summer and several months in areas with an extended winter.

Western honey bee a domesticated pollinator (the honey bee) could be compensated for by native, wild bee species." Similarly, Brian Dennis and William Kemp write: "Although the domestication of the honey bee is closely connected to the evolution of food-based socio-economic systems in many cultures throughout the world, in current economic terms, and in the U.S. alone, the estimated wholesale value of honey, more than $317 million dollars in 2013, pales in comparison to aggregate estimated annual value of pollination services, variously valued at $11–15 billion." On the other hand, P. R. Oxley and B. P. Oldroyd (2010) consider the domestication of bees
