Honey Bee Biology Adapted from Dr. Dewey Caron PowerPoint

What’s in a name? • Classification system Kingdom - Animal Phylum 2 of interest are..

Chordata – backboned vertebrate animals - includes humans Arthropoda – jointed limbed invertebrates that possess an exoskeleton - includes insects

What’s in a name? • Classification system Kingdom - Animal Phylum - Arthropoda Shared Arthropod characteristics are…. 1. Segmented bodies of 2/3 regions 2. Paired segmented appendages 3. Exoskeleton 4. Bilateral symmetry 5. Central alimentary tube 6. Open circulatory system 7. Sexual reproduction

What’s in a name? • Classification system Kingdom - Animal Phylum - Arthropoda Class Several Arthropod classes…Class insecta have.. 1. 3 body regions 2. One pair antennae 3. Three pairs of legs 4. 1 or 2 pairs of wings usually

What’s in a name? • Classification system Kingdom - Animal Phylum - Arthropoda Class - Insecta Order 30 + Insect orders – 5 largest are... 1. Coleoptera = beetles 2. Lepidoptera = butterflies & moths 3. Hymenoptera = bees, wasps & ants 4. Diptera = flies 5. Heteroptera = bugs, aphids, etc

Insect Sociality • EUSOCIAL – Cooperative care of young • Pheromones or trophyllaxis

– Reproductive division of labor • Caste system

– Overlap of generations caring for young • Often elaborate/defended nests

The 3 adults - Queen Reproductive female

2 functions 1. Lay eggs

2. Produce chemicals Bk Educ Service Photo

The three adults - Drone Male sex – not caste Mate with new queen (= virgins)

Perhaps contribute to “normalcy”?

Hive Bee “Work” • Includes… – cleaning – nursing – nectar ripening & honey storage - pack pollen - secrete wax - guarding

What is a Honey Bee?

• Answer … one of three adult forms each with own tasks (Division of labor) queen honey bee, worker honey bee drone honey bee

What is a Honey Bee? ►Answer ….. one of three adult forms each with own tasks (Division of labor) ►Answer ..... worker bees who perform different tasks according to age and gland development Hive bees such as cleaning worker bee, nurse bee, nectar ripening bee, wax secreting bee, guard bee Field bees foraging for nectar/pollen/water/propolis

BUT ALSO…… … one of three development stages (=brood)

Communication • •

Honey bees eusocial Prof von Frisch discovered their communication basics • A bee discovers a food source…. she returns home to tell her sisters

where it is, how far, & how good !
