It belongs to the insect order Diptera. Common members of that group are flies, mosquitoes, midges, crane flies. Your creature doesn't fit the size or shape of potential pests of the order Diptera. Usually, very small fellows such as yours are simply part of the food chain. So, you say that you have a cloud of them flying in the yard. Sounds like a recent emergence of non-pests.

Not Atlantis because your image has no black outer FW margin; not Aphrodite because paler submarginal HW band is too broad. The broad paler tan HW band (as opposed to the darker cinnamon color of the inner hindwing) is a distinguishing feature of the Great-Spangled.

Ichneumon wasp, the only thing I can find with the matching wingspots, dark antennae, and striping is: https://bugguide.net/node/view/1227057/bgimage https://bugguide.net/node/view/1094990/bgimage

It should be explained that Chinese mantids are a completely equal opportunity predator. They are very successful killers of bees, butterflies, and other beneficial insects. In warm climates, they will grab anoles and small amphibians. There are numerous videos online of these big Chinese mantids capturing hummingbirds at feeders. I began eliminating these insects from my gardens many years ago, as I rely heavily on beneficial insects in my gardens and adore watching my flower areas so alive with butterflies. Once I began to notice piles of butterfly wings under my annuals and perennials......that was IT! The much smaller native mantids don't cause these issues. Unfortunately, these big, imported bad guys also attack and eliminate our native species.
