Similar to recent observation on 21st May ?

Great photographs - these look very similar to a recent observation of small flies on sycamore tentatively id'd as Agromyzidae (Leaf Mining fly) by David Notton http://www.ispot.org.uk/node/264879?nav=users_observations

Chloropidae

They do look similar. These are Chloropidae, with the shining ocellar triangle. That is the right family for Thaumatomyia.
