Well, to be honest: it fooled me at first sight as well.
The convex third antennal segment (syn of succincta = curvicornis !)
is not obvious because of the angle of view in the first picture.
Moreover, the palpus is out of focus, but it is clearly both large and black.
A larger (that is, around 10 mm. or more) 'ordinary looking' Tachinid with as special feature a bluish tinge on the abdomen, is, as a rule of thumb, either Epicampocera succincta or Pales pavida.
And Pales has reddish tibiae ...
