This video is called Stomorhina lunata.
Translated from the Dutch entomologists of EIS Kenniscentrum Insecten, 20 October 2014:
This year so far has seen 48 Stomorhina lunata flies in the Netherlands, far more than in recent years. Most have been reported in the southern half of our country. In 1990 the first individual was seen in the Netherlands and in recent years there was a slight increase, but this year marks a huge leap. Stomorhina lunata originates in (semi-) deserts in southern Europe and Africa, where it is parasitic on eggs of locusts.
