Life cycles of insects: Exopterygotes and endopterygotes
By: M E Skeel
There are a bewildering number of insect types in the world but they all basically go through one of two types of life cycles. The more primitive types are called the exopterygotes, a word that simply means their wings (pterygota) develop on the outside of...
Behavior and ecology of insect parasitoids
By: M E Skeel
It is dangerous to be a caterpillar. Not only are they and other maggots, grubs and insect larvae subject to predation by birds, small mammals and reptiles but they face an even creepier danger from other insects. Wasps. in particular, have developed a method of...
A look at the extinct MOA
By: M E Skeel
Imagine a world without mammals, a primeval world of cool, wet forests filled with mosses, ferns and lichens and inhabited by flightless birds. This was the world of the Moa, in New Zealand before the coming of human beings. For millions of years, New Zealand...
Overview of Dugesia

Dugesia are flatworms, belonging to the invertebrate phylum Platyhelminthes. These worms are the simplest forms of animals that have three cell layers: an endoderm (gut) layer, ectoderm (skin) on the surface and mesoderm (muscle) in between. Flatworms are unsegmented, bilaterally symmetrical and worm-shaped, with a...
Life span of a dragonfly

The Order includes four families. The family Acrididae includes the short horned grasshoppers and the true locusts. The other three...
Understanding ant behavior
By: M E Skeel
Ants may be small but they are one of the most numerous and successful families of animals on the earth. They are also widespread, occuring in practically every terrestrial ecosystem, although they are most common in the tropics. They are insects, so they have six...
Biology of the Amoebae
