Spiders vs. Insects
What is Difference between Spiders and Insects? Despite the similarities in appearance is concerned, the truth is that spiders should not be confused with insects; since although it is true that they are distantly related to the latter, it does not cease to be true that they belong to another order.
Difference between Spiders and Insects
It is probable that up to now you have lived by believing that spiders are insects, and you still do not understand well what makes them different; if this is the case or you just want a little more information about it, continue reading, because then we explain to you what is the difference between insects and spiders.
To begin with the spiders belong to the order Araneae and are animals of eight legs, whose body is constituted by two parts: a cefalothrax (head and thorax combined) and an abdomen.
Also, spiders have simple eyes and cannot fly; but they can generate (without exception) the known silk threads (although not all of them build “spider webs” with their particular web forms). On the other hand, the spiders do not have antennas and their feeding consists precisely in insects.
As for the insects, the same as the spiders belong to the edge of the arthropods; but not to the order Araneae. They are characterized by having 6 legs, wings (in many cases) and antennas. They use the latter to be able to smell, while the spiders smell with their paws.
The body of insects is divided into three parts: head, thorax and abdomen. Their eyes are composed and most are not able to make silk threads as well as make spiders. Finally, the feeding of the insects is very varied; eat from plants to other insects. They present metamorphosis, something that is not observed of the spiders.
