Why are insects very interesting as objects of study?

Insects are the most abundant animals on Earth. Over a million different types of insects have been identified. They live in almost all situations or habitats on earth. Insects have lived on earth for over 300 million years. If you take the time to closely observe them, you will find them very interesting. No matter where you live or what you do, you can find insects. They can live in almost any situation or climate. Some insects eat our crops or food in storage; others may bite us, our livestock or our pets. Some insects are good for us by producing products that we can use (like honey), by pollinating our crops, or by attacking insect pests. Most insects, however, are irrelevant to our well-being, except that they are interesting creatures to watch.
