| Beetles | | ... that they do not solely comprise head, chest and abdomen. The second section consists solely of the prothorax, of which only the neck shield on top of the body is evident. The remaining two sections of the chest, together with the abdomen, form one unit, which is overlaid by the first pair of wings (the cover wings).
Beetles can vary enormously in size ranging from 170 mm in length (Titan beetle in Brazil) to lengths of 0.5 to 75 mm (European species). The largest beetle in Germany and Centra... | | |

Some examples of species of moths are: Arctiidae, Endromidae, owlet moths (Noctuidae), Cymatophoridae, picture-winged leaf moths (Thyrididae), eggars, snout moths or lappet moths (Lasiocampidae), Lemoniidae, saturniids (Saturniidae), hook-tips (Dre... | | |
| | The head and chest form one unit (Prosoma). This is followed by the abdomen which is usually significantly bigger. Araneae are Chelicerata. At the end of the head are retractable claws, containing glands which secrete poison. They do not use theit mouthparts (at the male as genita... | | |
| | In contrast to spiders the head, chest and abdomen form one unit. Harvestmen have neither spinning glands nor poison glands.

| | As in all Apocrita, the thorax is merged with the first abdominal segment, forming a unit called the mesosoma. The 4 segments of the mesosoma are blended together seamlessly and surrounded by a hard shell (exoskeleton) that provides effective protection against stings from bees or bumble bees when in their nests they are parasitizing ... | | |
| | Arachnids, in contrast to insects, have 8 instead of 6 legs. Instead of compound eyes arachnids have 8 simple eyes. The head and chest are one unit (prosoma). The prosoma is followed by the abdomen which is not divided and mostly appears in a bigger size. They are a member of the subphylum Chelicerata having the chelicerae – the appendages which appear before the mouth - which give the group it... | | |
