Thread subject: Diptera.info :: Small Tachinid from Holland

I also found this nice small Tachinid fly in the dunes of Holland (Amsterdamse Waterleiding Duinen). It is feeding (I suppose) on Rubus caesius, so that way its small size is easily appreciated (1 petal long). I guess its a Tachinid because of its bristels, I have no clue otherwise. Can it be IDed?

Very dry sandy area, partly open sand, partly herbaceous grass land, partly wooded with shrubs. Isolated trees nearby, forest close by.

Mintho rufiventris, I think:D

This fly is quite unlike the photographs in the gallery. Is it that variable, or might it be an other species?

Mintho is not very variable, in my experience - but I feel this is more likely to be a Cylindromyia - Theo will know which it is most likely to be in Netherlands :)

I am not Theo, but this must be Cylindromyia pusilla.

Unfortunatedly typical features not visible on picture. But size and locality are typical.

Well, in recent years C. interrupta has become common in the dune area in the Netherlands.
BUt I agree with Liekele, this is most likely C. pusilla (also not rare in the dune area).

So, should I hedge it with 'cf'?

Thanks for all input. At least I'm in the correct genus now!

Well, I', 98 % convinced it is pusilla.
That is, if you didn't photoshop it toom much (the colouration).

No, I didn't change the colours at all. At least at my screen it is like what I saw. In what way does interrupta differ? May be some other photograph gives a further clue...

Formally, some bristles are different
(1 sternopleural in pusilla, 2 in interrupta).

However, interrupta is slightly more orange coloured.
It's subtle, don't try this at home !
