Insect identification 4, a step by step guide
to identify insects to order level
This identification key works for adult insects found in Europe. It may also work for insects found in other parts of the world. All you have to do is click on the right choice in each box. This will take you to the next box, or to the page dealing with that order of insects.
Tiny insects with many (at least 12) segments to the antenna (see below). Go to Psocoptera, the book and bark lice.
Insects with fewer than 10 segments to the antenna (see below), and piercing/sucking mouthparts. Go to Hemiptera, the true bugs.
Insects with a twig- or leaf-like body (see below). Go to Phasmida, the stick and leaf insects.
