Sorry to forget. In high resolution there is a gap in C near connection with Sc, like in case of Pallopteridae

Opomyza (Opomyzidae). Feel free to correct me;)

Hi Nikita,
This is a female of
Opomyza punctella [Opomyzidae]. For me one of the better species of the genus
Opomyza. Could you tell me a little more about the location on which you found it?

Hi Jan, hope you don't mind if I reply to your question for Nikita;)
I've found this species twice on the southern coast of Finland: on an army helicopter field (open sandy area with VERY nice
Thymus-dominated vegetation), and one a landfill, with some blotches of vegetation typical for dry meadows among more typical ruderate stuff.

Hi Kahis and Nikita,
Thank you for your responses to my question. First of all I don't know anything about the messaging of the tip of the abdomen.
Opomyza punctella is said to be rare throughout it's range although especially from Finland rather many localities where it has been found are recorded. The host plant of this species is still unknown. Most probably it will be a grass since all known host plants of the other species are grasses.

1. I mean "massage of the tip of the abdomen by the 3-d pair of legs". When I observed this fly it seemed to me that it may be something concerning oviposing.
2. Next weekend I'll do my best to find Opomyza punctella and check which plants she visit and so on.

Hi Nikita,
The "messaging" was just a typo (;)), I meant to type "massaging". And I know nothing about this behaviour. It is interesting though! Since I don't spend much time in the field, I hardly have any information on the behaviour of Opomyzidae. Any information is more than welcome!! If you have more information on the massaging behaviour (or any other behaviour for that matter), please let me know!

Hi Jan.
This weekend I find and investigated place.
The plant on which Opomyza punctella spend all 20-30 min of my observation was Phleum pratense.
