One of the Good Guy Bugs.

This is a peaceful wasp that does not sting. It searches out insects to feed its larvae.

In the case of this particular wasp, it prefers grubs for it's prey. It digs a burrow and places the grub inside it after laying an egg in it.

Clearly a benefit to gardeners, this wasp should be encouraged to live in one's garden.

These bugs are all over the flowers on our overgrown mint patch. There is a mass of them flying low to the ground. They just get out of the way as I walk through them.

The only problem I have is that it is digging up my backyard. I have little tiny heaps of dirt that multiply by the dozens overnight. I am not exaggerating. Last year I had to have pest control out and this year it is beginning again. I think I may try some Sevin myself. harmless or not they do not make the grass look great!

I am glad to hear they are non-stingers. I was mowing the lawn and noticed the golden rod I passed very close to was covered in these. I did not notice them digging so they must have been getting insects from the plant.

Have lived in this area all of my life & don't remember seeing these before. They look like the "kropit" picture and have 2 black wings. They just keep flying low to the ground, even when I am mowing. They do seem to like the small wildflower patch we had in the backyard this year and don't seem to stray very far from it. Glad to know they are beneficial.

You DEFINITELY want this wasp in your yard. The favorite food for the larvae is the Japanese Beetle Grub. The female somehow locates an underground grub, digs underneath it and lays an egg on it. The egg hatches and the grub is doomed! If you see these in your garden, you also have an infestation of Japanese beetles.

They are also very timid - you can brush them off a plant and not get stung.
