Black winged bug- Sepsis genus - ensign flies

Observation - Black winged bug- Sepsis genus - ensign flies. Description: Very small black winged bug (ant?) with two small black spots on its wing - one on either side. Helpful identifying character I hope found on farmland in a holly busy and hawthorn hedge with ash trees around.
