Scorpions and insects similarities
These animals both belong to the phylum Arthropoda. It means that scorpions and insect both possess paired and jointed legs.
They also have exoskeleton that make their body hard and protected from environmental stress such as heat and desiccation.

Scorpions and insects differences

Scorpions are classified under class Arachnida – animals under this group have eight legs, just like spiders!
On the other hand, insects have six legs and they are classified under class insecta.
Remember this: animals with eight legs are arachnids while animals that have six legs are called insects! You don’t have to be confused with this!
Arachnids like scorpions have two body segments called the cephalo-thorax (head +thorax) and abdomen. Insects have three body segments namely: the head, thorax and abdomen.
Insects possess a pair of antennae, scorpions don’t!
Majority of insects species develop wings, scorpions do not!

What is the difference between scorpions and insects?
Insects possess three main body segments with six legs, 1-2 pair of wings and a pair of antenna while scorpions are arachnids with two main body segments with eight legs, no wings and antennae.
