Photographed in Reading, UK, on 2011-07-23.
Both have a long thin proboscis so they must be
Conops not
Leopoldius.
But which
Conops species are they?

With the help of Mark van Veen's Conopid key (
http://home.hccne...index.html), I now think these are
Conops quadrifasciatus.
Of the
Conops species on the UK list (
http://www.dipter...p?id=11957): the all-pale femurs 2+3 exclude
C. caeriformis,
vesicularis and
strigatus (
vesicularis would also be reddish).
The black scutellum and the just-visible 'silver stripe' on the thorax (just behind the wing bases) exclude
C. flavipes.
