1. Where are the eggs deposited? What is the number of the eggs? How soon do they hatch?
  2. What is the food of the larva or nymph? Are the food habits of the insects harmful to man? If so, how?
  3. Describe the larva as to form, color, and appendages. Is it capable of locomotion?
  4. Is the metamorphosis complete or incomplete? If complete, describe the pupa and tell where it may be found.

Drawings.

There should be one drawing of the insect to show its general characteristics; usually a dorsal view is best. For other drawings ask your instructor.

8. A REVIEW OF INSECTS

Directions.

The answers to questions in this study may be conveniently written in the form of a table. Construct this table by placing the topics at the left and the names of insects at the top. Allow ample space, about one half inch for the horizontal spaces and one and one half inches in width for the vertical columns. Use one or two insects from each of the principal orders, letting the table extend across two opposite pages.

Topics.
  1. What is the habitat?
  2. What regions has the body?
  3. How many antennæ? What is their form?
  4. What kinds of eyes has the insect? How many of each kind?
  5. How many legs?
  6. For what kind of locomotion are the legs adapted? Which legs are thus used?
  7. How many wings? Membranous or thickened?
  8. What is the position of the wings when at rest?
  9. If the fore wings are thickened, what is their texture,—leathery, smooth and sheath-like, partly membranous, covered with scales?
  10. What kind of mouth parts,—jaws for biting, a beak for piercing, a tube for sucking, adapted for both sucking and biting?
  11. By what means is respiration accomplished?
