Anyone ever have any garden damage from sawflies? I've been watching a number of solid black wasp looking things in my garden. They typically would sit on a cucumber leaf or squash leaf and then fly away. I thought maybe they were some form of predatory wasp looking for bugs on my plants. I finally identified them as sawflies which lay eggs on the under sides of garden leaves. The eggs result in tiny larva which eat the edges of the leaves away. I haven't been able to identify any plant damage from them, but they are there.
