My first blog post - July 9, 2006 - was on spittle bugs. I didn't have my digital camera then. So now that they are back, I can show you. As I said, it looks like really clean spit. Inside is a little bug that creates all this stuff to keep wet and protected. It's easy to spray off with a hose and apparently the little guys don't do much damage.
However, aphid are a different story altogether. Here the larvae (at least I think these are aphid larvae) cover the soft, green shoots of our thalactrum. Well this plant is pretty easy to deal with - I just use the jet level on my hose attachment and blast the plant. It's hardy enough that the water doesn't break it, but the aphid are gone. When they get into the birch trees it's another story. There were a few years back when the yard was covered with black syrup dripping from the birch trees. It wasn't so bad last year and so far this year seems ok.
