You couldn't go for a walk that spring without these things falling on you. The read danger, however, was to the trees. They tend to cover a whole tree in their webby tents (with the trees looking much like your spider web photos), and will eventually consume all the leaves and kill the tree. Interestingly, you don't need pesticides or anything sophisticated to save the trees, just a very long stick. Simply poking a hole in the tents will allow nature to take its course: wasps think those caterpillars are quite yummy. Once a hole is poked in the tent, the wasps find it and have a rich dining experience. Ever since then, I've kind of liked wasps, though I still battle keeping them from nesting near the doors and windows of my house.
An argument is two people sharing their ignorance.
A discussion is two people sharing their understanding, even when they disagree.
Thats so cool! I have always thought that spiders were the greatest, always had a bit of an odd fascination with them. There are so many of them, and yet they are able to hide the fact that they are there by burrowing and slipping into crevices. They are hidden in plain sight. So common yet so different from each other. And the webs, so beautiful and entricate, able to entice their prey. The spider can set up a plan, and at the end of the day can claim plausable deniability when something does not use foresight. They are the silent predators, the little bandits. Just awesome, wish I could have been in austrailia to see that.
