My first post, thank you for letting me in. I am a retired biologist from Lier, close to Oslo, Norway. I am not specialised in Diptera, but encounter a lot of interesting flies. I try to contibute by taking high quality pictures of insects with focus on identification.

In this case I have a fly from my garden photographed on July 25. that should be a Dexiosoma caninum, but it has wings all yellowish and som yellow spots on the abdomen. I haven't found anything similar in pictures of Dexosoma caninum on the internet. Is it an anomaly or could it be another species?

(How do I add a second image?)

Welcome jenygard! At a first glance it looks good for Dexiosoma caninum, but a dorsal view of the thorax and a lateral one of the head would help to be sure.

Sure looks like the male of Dexia vacua, which is pretty rare !

Sorry for late reply. I have been away for a week. Thank you for the answer. That is very interesting. I find only 5 very old records of Dexia vacua in the Norwegian database of species (Artsdatabanken.no). I will follow up with Norwegian dipterists.

Third picture of this fly, a little more from the side.
