🕷️ Bug of the Week: Spiders!

Spider on a leaf

Did you know spiders are not insects? Spiders belong to a special animal group called Arachnids. One of the easiest ways to tell if a creature is a spider is by counting its legs. Spiders always have 8 legs, while insects only have 6!

A spider’s body has two main parts:

The cephalothorax (head and chest combined)

The abdomen (where silk is made)

Unlike insects, spiders do not have wings or antennae. Many spiders also have 8 eyes, although not all spiders see very well.

One of the coolest things about spiders is their silk. Spider silk starts as a liquid inside the spider’s body. When the spider pulls the silk through tiny organs called spinnerets, it hardens into a strong thread. Spider silk is incredibly stretchy and even stronger than steel for its size!

Many spiders build orb webs, the large circular webs you may see in bushes or gardens. First, the spider creates a bridge line by letting the wind carry a silk thread to another branch. Then it builds spokes like a bicycle wheel before adding sticky spiral silk to trap insects.

Some spiders don’t build webs at all! Wolf spiders and jumping spiders hunt by chasing or jumping on their prey. Even these spiders still use silk as a safety rope called a dragline.

Spiders are important helpers in nature because they eat many insects that can damage plants or become pests. Next time you see a spider web sparkling in the morning sun, take a closer look at the amazing engineering skills of these tiny builders!
