This is
Chorisops tibialis. The flight period for
Sargus and
Chorisops tends to be through the whole summer in Britain - in Portugal, they may avoid the the very driest time, so may be a bit later there. The only real autumn species is
Sargus bipunctatus which regularly flies from August through to October.
