One of the talks yesterday was by Dr. Doug Tallamy whom we profiled in the Nov/Dec 08 issue of Washington Gardener Magazine. He got some plant folk in the room riled up with his tent caterpillar defense. In his opinion their entire defoliation of a tree is no biggie and should be tolerated as the trees re-grow their leaves fairly quickly. He thinks the tent caterpillars are a terrific bird food source and besides they are native to this area. He has a point and some research to back him up in that the trees do recover from the denuding, but upon further reading I find that if they attack fruit trees this disrupts the fruiting cycle and doesn't that mean someone else's food source is hurt down the line?
Back to the layout deadline grind and escorting more stinkbugs from my home.
