Insects are so numerous that it is
impossible to count them. They are
so varied that not one of them is
really typical. Almost all ofthern
are small. If they were not, there
would hardly be any room for
anything else on earth !
Because insects are so numerous,
they are easy to study. Even the
smallest "creepy-crawly" insect
is sure to have some interesting
aspects of behavior.
Did you know, for example, that
greenfly give birth to live babies
for most of the year--and without
mating with males? And did you
know that ants keep a "dairy herd"
of greenfly for their"milk," just
as a farmer keeps cows ?
Did you know that many"wasps"
are harmless, stingless beetles
that mimic the wasp for protection
from enemies ? Or that the hoverfly
is the ace aeronaut of insects,
able to move in any direction
while in flight--even backward ?
And did you know that stick insects
and twig caterpillars so cleverly
copy sticks and twigs that they
might almost be the real thing ?
These are just some of the
exciting subjects dealt with in
this book. There is also a reference
and projects section at the end,
packed with more information
and practical suggestions.
