Honey Bee Biology
Adapted from Dr. Dewey Caron PowerPoint
What’s in a name?
• Classification system
Kingdom - AnimalPhylum
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 - AnimalPhylum - ArthropodaShared Arthropod characteristics are….
1. Segmented bodies of 2/3 regions2. Paired segmented appendages3. Exoskeleton4. Bilateral symmetry5. Central alimentary tube6. Open circulatory system7. Sexual reproduction
What’s in a name?
• Classification system
Kingdom - AnimalPhylum - Arthropoda
Several Arthropod classes…Class insecta have..
1. 3 body regions2. One pair antennae3. Three pairs of legs4. 1 or 2 pairs of wings usually

What’s in a name?
• Classification system
Kingdom - AnimalPhylum - Arthropoda
30 + Insect orders – 5 largest are...
1. Coleoptera = beetles2. Lepidoptera = butterflies & moths3. Hymenoptera = bees, wasps & ants4. Diptera = flies5. 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 chemicalsBk 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

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 !
