Utah State Insect

European Honeybee (common name)
Apis mellifera (scientific name)

Overview

Honeybees are one of the most common insects in the world. They are extremely important in agriculture for their ability to pollinate plants and also contribute to the economy in terms of honey and beeswax. The European honeybee was named the state insect of Kansas (in 1976), Louisiana (1977), North Carolina (1973), Maine (1975), Missouri (1985), Nebraska (1975), New Jersey (1974), Utah (1983), Mississippi (1980), Georgia (1975), South Dakota (1978), and Wisconsin (1977).

PHYSICAL DETAILS

Honeybees have compound eyes comprised of hundreds of smaller eyes called ommatidia. Worker bees are 0.37-0.62 inches (9–18 mm) in length and have a pollen basket on their hind legs, four pairs of beeswax-secreting glands on their abdomen, and an extra stomach for storing nectar and honey. Only females have stingers that they use when threatened. Worker stingers can be used only once, unlike those of queen bees. Worker bees are golden brown and black in color with a black head and patches of pale orange. Their abdomens and wings are covered with yellow bands and their entire bodies are covered with tiny hairs. Queen bees are much larger (0.75 inches or 20mm) than other bees and have a longer abdomen.

Larvae: Eggs hatch after three days into a white larva. After another six days they become pupae.

LIFESPAN

The queen bee lives as long as five years. Drones live for eight weeks. Worker bees born in summer live for around 6 weeks, and those born during the fall live until the next spring.

HABITAT

Range: Honeybees are found all over the world except Antarctica.
Flight period: Most active during spring and summer.
Conservation status: Least concern

BEHAVIOR

Honeybees are very social in nature and exist in a very structured social system that has three specialized groups: the queens, the drones, and the workers. Each of these "castes" has their own function. The queen’s main function is to lay eggs, and she can lay more than 1,500 eggs per day. Drones exist only to mate with the queen bee and either die or are driven away at the end of the season. Worker bees take care of building and maintaining the hive and honey comb and also take care of the queen and defend the hive.

Older workers, also known as field bees, gather nectar, water, pollen and plant resins that are used to build hives. Once the bee colony gets a new queen, it subdivides in a process known as "swarming," during which the old queen moves out with half of the bees to build a new colony. Honeybees are not usually aggressive, but they react when their hive is under attack. Eggs have to be incubated at 94 degrees Fahrenheit (34 degrees Celsius), and the bees maintain this temperature by depositing water and fanning the hive with their wings during hot weather. In winter, they cluster close together to generate heat.

DIET

Adults: Flower nectar and pollen form the main diet for honeybees.
Larvae: Young queen bees are fed a special jelly that is made using glands in the heads of the worker bees. Only bees that are fed this special "royal jelly" develop into queens.

TRIVIA

The size of honeybees depends on the size of their colonies. Smaller colonies have just one large queen and tiny other bees, but as the summer ends, bigger honeybees are produced due to larger colonies.
Only one queen reigns over a hive. The other weaker queens are stung to death by the reigning queen bee or by the workers. Unfertilized eggs become drones.
Hive activity is regulated by a scent produced by the queen bee.
