After you have completed this unit you should know for each order:
•its common name, order name, and meaning of the order name
•its development, or metamorphosis
•3-4 facts regarding its life history and/or economic importance
•its wing type, leg types and mouth adaptations
How do you tell the
a bee and a beetle?
The answer to the question, "What is the difference
between a bee and a beetle?" may seem easy. But
when you really think about it, it is a challenge to
describe the difference to another person. They both
have wings, six legs, and antennae. You can't just
say, "Well, that looks like a bee and that looks like a
beetle." There is more to it than that. By the end of this
unit you should be able to tell someone without
hesitation the difference between these two insects as
well as many others.
As you progress through the unit, you will refer to the
textbook for information to fill in your study guide table.
The textbook has a appendix dedicated to describing
the insect orders, but more detailed descriptions are
scattered in textboxes throughout chapters 7-14.
You should recall from previous units how organisms are organized. An
organism is first classified into a Kingdom (such as Animalia, Plantae,
Fungi, etc), then Phylum, Class, Order, Family and lastly Genus and
species. You have already learned that Insects are in the kingdom
Animalia and the phylum Arthropoda along with lobsters, spiders and
crabs. You also know that insects are in a separate class called
Insecta. The class Insecta is then broken down into 30 insect orders
and these orders are then separated into families. For example, a
scarab beetle is in the class Insecta, the order Coleoptera and the family
Scarabaeidae. A bee is in the class Insecta, the order Hymenoptera,
and the family Apidae. This lineage is diagramed on the next slide.
