Die after mating • ~ 17 Drones may mate with Queen during her mating flight. • Get “kicked out” of hive in winter. Queen • Mature female that received abundant amounts of royal jelly while as larva • Can live 2 – 4 years • Can lay up to 2,000 eggs per day during spring build up. Metamorphosis of Queen Bee – Egg hatches on Day 3 – Larva (several moltings)Day 3 to Day 8½ – Queen cell capped~ Day 7½ – Pupa~ Day 8 until emergence – Emergence~Day 15½ - Day 17 – Nuptial Flight(s)~Day 20 – 24 – Egg Laying~Day 23 and up Swarming Eventually, the worker bees decide that • the queen has become too old or damaged • Or that the hive is physically too small So… They decide to make a new queen(s)
