Engineering marvel:

I'm no great lover of spiders and other creepy-crawlies but, I've just I've just looked out of my kitchen window and, glistening in the bright sun is a spider web that stretches from the guttering just above the window (its a bungalow) to a part of the garden fence some fifteen feet away...how does it do this? The quite small spider is just sitting in the middle of its web, red eyed and dripping fangs, just waiting for me to walk into the web when I go out to cut the grass.
Experience; is something you gain, just after you needed it most.

When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.

There is a nice animation here which shows how they do it. Still a wondrous process.

Re: Engineering marvel:

i have sercret love of making spiders think they have baged them selfs a catch. dont know the name of the spider but the ones that hide in a hole an make a small web around the outer edge of the hole are my fav.
wolfspiders a pretty gd at getting about once they have hatched they will find a high point attach a string web down then send a length out with them on the end and once they get a bigger enough updarft they will relese them selfs to let the wind take them to pastures new

Would you believe its called a funnel web, had some in my garden,  But if you are in Aus dont go near then, very poisoness.
In my samll front garden 10x30 ft  I am getting at least 15 web with large spiders every day, must be a lot of flying insects around, just going out to try and get a pic

Re: Engineering marvel:

If I ever catch a fly in the house I like to release them in to a spiders web and then watch how they wrap them in silk.

Re: Engineering marvel:

The damn things scare the willies out of me but even i'll admit they're fascinating when it comes to how they get about and build webs.
Scary looking suckers tho
