Classification of insects.

Insects are metamorphic animals.

The term “metamorphosis” refers to changes in body appearance in insect kingdom. Common insects can be roughly divided into “complete metamorphosis” and “incomplete metamorphosis”:

I. Complete metamorphosis

The growth process of insects can be divided into four stages: eggs, larvae, pupae and adults. Baby silkworm (moth) is the standard complete metamorphosis, and the appearance of larvae and adults varies greatly.

2. Incomplete metamorphosis

The process of growth can be divided into three stages: egg, larva and adult. Like mantis, it is typical of incomplete metamorphosis. The difference in appearance between larvae and adults is whether they have wings or not.

Classified according to human preferences

There are many opportunities for humans to contact insects in daily life, so what is harmful to humans is “pests”, such as aphids that suck lettuce, and what is beneficial to humans is “beneficial insects”, such as ladybugs that specialize in aphids.

Classification of Biologists

All living things are classified into seven classes: boundary, phylum, class, order, family, genus and species. Insects are classified as Insects, while all kinds of insects are classified as 31 orders. For example, Tigerhead bees belong to Hymenoptera and ladybugs belong to Coleoptera.
