Insect Body Parts
Insect Body Parts
Insects all have the same general structure.
They have segmented bodies divided into three
regions: head, thorax and abdomen. They have
segmented legs and usually have wings attached
to the thorax. There are also other body structures
that are typical of insects. However, there are
variations in body structures, and each order of
insect has variations that are characteristic for that
order. In the following exercises you will learn
some of the characteristic variations that are
typical for two orders of insects. Doing the
exercises will help you understand why insects are
placed in a particular order even though some of
them may, at first glance, look like insects in other
orders.
Before doing the exercises on the true bug
(Order Homoptera) and the beetle (Order
Coleoptera), study the two illustrations below to
review the general structure for all insects.
