How do spiders create web across two different trees?
In: 20
They attach it on one tree and jump towards the other. If the wind is right, they succeed. Otherwise, they try again until they succeed.
They have some options:
They can drop a loose line and let the wind carry it to the other tree. They can attach a line to the tree they’re on, hang from it and let the wind carry them to the other tree. They can attach a line to the tree they’re on, walk across the ground to the other tree, climb up it and draw the loose line in until it’s tight between the trees.
They abseil on a non-stick thread, walk over, climb the other tree and eat the surplus thread.
They either carry it across themselves, like you would a clothesline, or they let out a string of silk and hope the wind carries it to another surface where the spider can anchor it properly.
