Phasia barbifrons is a small Tachinidae, which is normally rather rare in the Netherlands but abundant in some years. This years proves to be one of those. I just returned from a nearby forest and saw literally thousands of them.
I am very interested in the distribution of barbifrons in the Netherlands, since not specimens have been recorded (yet) west of my home, Soest.
Phasia barbifrons is easily recognized:
* very small, 3 -4 mm.
* on flowers, often Umbellifera, also Compositae
* black with red eyes
* eyes nearly touching on the vertex
* abdomen unusually broad and short

In short, it is a dwarf and black version of Phasia hemiptera.

All records are welcome: th.zeegers@tref.nl

You may find them till the end of August.

Good luck

Additional remark
As John Smit has pointed out correctly, there is yet one other Tachinidae that fits the diagnosis given above: Phasia pusilla.
This species is quite rare in The Netherlands, but could be found in the dune region.
So please collect any small Phasia when in doubt.
With a microscope, the difference is simple:
halters yellow -> Phasia barbifrons
halters dark -> Phasia pusilla

Thanks, John
