Minute fly, face barc west
These are perhaps Agromyzid flies. Not sure, but they are very tiny tiny tiny flies ( I used a 10X microscope lens and still have to crop the shots), which would fit their leaf mining lifestyle. There appear to be 2 species here. Let's pretend they are Agromyzids which gives me a chance to tell you that they are very picky. Each choosing to "mine" the leaves and stems of a small number of plants. Hidden biodiversity. Thank you little plants and flies. Collected on the proposed Maglev Trainyard site on the Beltsville Agriculture Research Station.
We Are Made One with What We Touch and See
We are resolved into the supreme air,
We are made one with what we touch and see,
With our heart's blood each crimson sun is fair,
With our young lives each spring impassioned tree
Flames into green, the wildest beasts that range
The moor our kinsmen are, all life is one, and all is change.
