Each spring, one of the first insects I see in the yard are these ichneumonids. They flit around the grass and low shrubs, just above ground level. They don\'t stay around long, though.\r\n\r\nAny idea what they might be, @bclaridge?

The first ones I've seen this spring. There were quite a few flying just above the ground in the backyard raspberry patch.
I netted one, cooled it down, took some (bad) photos, and released it.
