5. What is the type of mouth parts, biting or sucking? If you have living dragon flies, try feeding them flies or mosquitoes and note how they are seized. 6. The food of dragon flies is mosquitoes and flies caught while on the wing. In what various ways is the dragon fly specialized for getting food in this manner? _Summary._ How is the dragon fly fitted for its aerial life with respect to its body, means and method of locomotion, sense organs, kind of food and manner of obtaining it? _Suggested drawing._ a. Dorsal view, showing veining of one wing. 6. THE HONEYBEE _A Study of Adaptations for Community Life_ _Materials._ Preserved specimens of workers in small vials and in watch glasses, and some mounted specimens. A demonstration case showing the three kinds of members of the community, stages in the development of the workers and queens and the cells in which they are reared, specimens of the comb. Small pieces of beeswax, a box of honey, and specimens of comb free for examination. Mounted preparations of mouth parts and stings. Simple lenses and compound microscopes. _Observations._ _The Worker Bee._ 1. Observe and describe the form, size, regions, and covering of the bee. What are its colors? 2. Observe and describe the texture, veining, relative size, and position of the wings. Discover how the fore and hind wings are hooked together. What advantage in having them hooked together? 3. For what kind of locomotion are the legs best adapted? 4. Find the pollen basket on the tarsus of a hind leg. How is it fitted for carrying pollen? What are the wax shears? a. Examine and describe the structure at the posterior end of the body used for stinging. (Use a mounted preparation for this with low-power of microscope.) b. The mouth parts are fitted for both biting and sucking. Find what makes this possible. (Use mounted preparation.) 5. Describe the antennæ and the number, position, and shape of the eyes. Are the eyes fitted for keen sight? Give reason for answer. 6. The worker bee gathers honey and pollen and defends the entire community from enemies. What various adaptations fit it for this work? _The Community of Bees._ 7. How do the workers, drones, and queen differ in general appearance? 8. Describe the appearance of the comb and the arrangement and shape of the cells. Why this shape? How are the cells closed when full of honey? 9. How do the cells used for rearing worker bees differ from those used for rearing queens? What is the appearance of the larvæ? Of the pupa? 10. Examine and test in various ways a small piece of beeswax. What are the qualities possessed by this wax which make it suitable for making comb and protecting the home from storms?
