On oak tree sap. Clouded cross-veins, not sure if the tips of longitudinal veins are also darkened. Rather long winged and kind of hunchbacked. Abdominal pattern inconspicuous, darkend medial stripe on thorax. Suspected Hirtodrosophila, but those don't have clouded wing veins. Could this just be a pale D. immigrans?

Vienna, Bot.Garden, late September

The striped thorax is confusing. D. immigrans is not excluded, but I would rather say that it is a member of quinaria group (phalerata?, kuntzei?).
