The Difference Between Insects And Spiders ?
Despite the visual similarities between the two both are actually members of distinct families. Spiders are members of the Arachnid family whilst insects belong to the Insect family. So what makes the two families different ?
Well for starters spiders have 8 legs whilst insects have just 6. Insects have 3 distinct body parts, a head, thorax and abdomen whilst spiders have just 2, a combined head and thorax known as the cephalothorax and an abdomen.
As well as the above, other interesting differences include the eyes. Spiders have simple eyes whilst insects have compound eyes. Spiders have piercing jaws whilst insects have jaws which are more suitable for chewing. All spiders can make silk thread (although not all spiders spin webs) whilst most insects cannot. Spiders can’t fly where as many insects have wings allowing them to do so.
So yes to the untrained eye there is indeed very little visual difference but if you look really hard then they’re actually worlds apart.
Insects can’t make silk thread? Where do you think silk comes from?
Spiders can produce silk as can Silk Worms, neither of which belong to the Insect family. Insects are not able to produce silk. If you want to look further into this familiarise yourself with the Arthapoda Family and see what types of animals belond in which group.
According to Wikipedia and the Encyclopedia Britannica, silkworm moths are in the Insecta class.

I think you’ll find that silk worms (in spite of their name) are not worms but caterpillars of a moth, and therefore are technically insects. Whether or not the silk produced by them is the same as that produced by spiders or not I don’t know, but the method of production is different (spiders secrete from a special gland whereas the silk worm produces it from its mouthparts). To be fair to the original author, though, they do say ‘most insects cannot [produce silk]‘ so they were correct. Zoe on the other was clearly wrong… and can’t spell Arthropoda…and doesn’t know the difference between a Family and a Phylum
This is getting old, but the original article does say “MOST INSECTS CANNOT MAKE SILK”
And from the looks of it, I highly doubt that the Zoe Delphy that posted that comment is going to be the Zoe that wrote the article. Why would she write one thing in her article and then say the opposite in the comment MAKES NO SENSE.
Hey I’m Micheal Jackson btw lol
