Yesterday at the Old Reservoir near our house in Lexington, we (actually Amy) spotted a really cool-looking caterpillar on a tree. It was almost certainly a tussock-moth caterpillar, much like this one except that on ours the four distinctive tufts on the back were yellow rather than white. It’s a good thing I didn’t pick it up as I was tempted to do, because apparently the bristles can be quite irritating.
