The environment is a cork-oak (Quercus suber) and Aleppo pine (Pinus halepensis) forest, with holm-oak (Quercus ilex) along the temporary brooks, situated near the coast (less than 4km from the shore-line, about 25 m high). See link:

The flies were found always just beside the small ponds that remain in very few places of the dried brooks even at the end of the summer. They are very shadow ponds inside the forest, with only limited sun at about midday.

I have only noticed this species at the end of September.
