Where Have All The Normal Summers Gone, Paula Cole??

Every year the garden is different--though maybe you don't think so. Obviously, everyone's gardens are ahead of schedule; shoot, a few weeks ago I had asters blooming, and some eupatorium is just starting to flower a good two months early. Swamp milkweed bloomed in early June and never got pollinated. How do insects cope with this new cycle? I have seen fewer insects this summer--maybe I'm used to my garden blooming later (on time) when there are more insects, or maybe it's just a bad insect...
