Review for Exam II
The following is a list of subjects, terms, definitions, questions, etc. that you should be familiar
with for the second exam.
a comprehensive list of everything you need to know but is
provided as an aid to help you study.
You should know something (at least to the extent covered in
lecture) about the
morphology, development, biology and ecology of all of the orders and
suborders (where mentioned) and families and superfamilies.
need to know the scientific
names of the families covered in class but you do need to know their common names.
to be able to distinguish one family from another.
Consequently, you will need to recognize and know
something about the distinguishing characteristics (morphological, behavioral, ecological-how do they
live and where) for the important orders and important families we covered in the lectures, movies,
and discussion sections.
This necessarily includes knowing the unique behaviors (where mentioned)
for feeding (what and how do they feed on?), reproduction, predator avoidance, prey capture,
In general you should know which orders are a metabolous, holometabolous and
which are hemimetabolous (everything up to Thysanoptera is hemimetabolous, Thysanoptera are
weird, and everything after Thysanoptera is holometabolous).
Extensive use of the handouts (pictures
and text) should make these tasks somewhat easier. While studying, it may help to ask yourself the
following questions for each group of insects:
Where and how do they make a living?
What do they
What special structures are they equipped with that allow them to live the way they do?
What unique structures or characteristics (e.g. behavioral, reproductive, etc.) of this group can I use to
tell them apart from other groups? I do not expect you to remember the unique behavior or
reproductive method of every insect we have discussed.
you to be able to provide six
or seven different methods of mating, for example, i.e. of getting sperm and the egg together.
does they male find the female or vice versus. In some case the particular mating system may expose
the insect to some risk as for example the fly that attacks the crickets.
What are some of the defenses that an insect uses to escape its enemies?
System Natura what is it, what is its purpose, i.e. what function does it serve, and what do we mean by
a hierarchical classification system.
What does the classification level represent.
What is a scientific
name and how is it related to binomial nomenclature?
What are Trilobites and how are they related to arthropods?
You should know some other arthropods
besides insects and spiders and describe the characters that make them arthropods and how they differ
from other arthropods such as insects and spiders.
What are the four major events in the evolution of insects.
