As far as I can see they just wander about all day, where are its offspring? How come I never see a baby spider, is it simply too small?
I saw a spider continuingly trying to get up a wall and it kept falling off, and yet every single time it tried again and again.
Are insects devoid of emotions such as anger and compassion, would it be best to illustrate how they work by saying that they are like robots with preprogrammed reactions to their immediate environment?

Correction: Spiders are arachnids and not insects.

Spiders do have a lot of pre-programming, but many (most? all?) of them can learn too. I don't know about emotions; how would you be able to test or measure such things? Anyway, remember the goal here - make as many successful kids as possible ('successful' being defined as producing as many kids as possible in their turn). The more food you eat, the more and bigger eggs you can lay (if you;re a female); the more females you can mate with, the better your chances of producing more kids (if you're a male). So female spiders concentrate on catching and eating as much as they can, while male spiders concentrate on growing up as quick as possible, and then running around like maniacs finding females and hoping they survive long enough to mate as many times as possible. There's a lot more too it than that, but that's basically it; the rest is details...
Oh, and if you want to see baby spiders, now is the best time - go out early on a nice warm fall morning and you may be lucky enough to find a cluster of spiderlings preparing to 'balloon' from the location of their eggsac. They climb up to the top of whatever object is nearby, let out a strand of silk and let the breeze take them wherever it will. Weedy fields are good places to look for this.

Spider questions
1. They wait for food or go looking for food, or build webs all day.
2.Different spiders rear their young in different ways. Some spiders carry their young on their backs when very young. Some just lay their eggs in a nest and never go back. You don't see young because you don't know spiders. The young are just smaller versions of adults.
You may say that spiders have simple minds and only have a single reaction to any situation. But I can give you many situations that all humans will react exactly the same. Like us they have evolved to do things that are most advantageous, but I do not think they are done evolving so some must do things different to similar situations so that a best can be selected for.

I noticed a small fast spider today in my bathroom sitting on the same spot along the edge of the bath tub for most of the day. I thought it might be dead because of how long it sat in the same spot. When I returned to the bathroom this evening it had moved. A few minutes later I saw it traveling along the wall towards the front of the bathtub. It traveled to the chrome faucet and was traveling over and over again all around the faucet. It seemed to be going in circles and it just made me wonder what was on it's mind to keep going in circles over a chrome faucet. I figured maybe it was just bored or it had a lot of energy to burn off because it just kept moving in circles. And then again it may have just been a dumb spider making no sense.

I was watching a programme on TV the other day and they said all the spiders in the world eat the equivalent of the weight of the UK population in insects every year.
It also said there is about 2-3 million spiders per acre of land in the UK

i have a spider so i think i can answer, spiders spin a web, spend the rest of her life waiting for a prey to attach itself. this way it can remain alive for weeks without food since it doesn't waste a lot of energy. when it is threatened or old enough it spinns a web around it and in two days you '' notice about 100 small spiders wondering about.. survival of the fittest ( the few)

Eat, sleep, s**t, spin webs, try to crawl up walls that its got no hope with. I suppose they do the same things over again because they're dumb and have very little memory.

Whenever hungry they are always on the look out for food.If you throw a piece of paper at them they will pounce on it only to realise it is not food.It will catch anything that moves.
