Many insects resemble others insects in shape, color and even sound. This is called mimicry . For example, many harmless insects are banded in bright yellow and black, resembling a stinging wasp or bee. They may have defensive chemicals that make them unpleasant to animals that may want to eat them. A special collection of this type might be of insects that all share the same coloration or appearance.
Many insects try to camouflage their features, to avoid being found by birds or other predators.
Some have colors and patterns that help them blend in with tree bark, the soil or leaves. Other insects may even take on the shape of twigs or leaves. A specialty collection of this type may include various insects that use camouflage. If possible, you may also wish to include examples of materials that the insects attempt to mimic. One of the reasons there are so many different kinds of insects is that most have specialized habits.
