Yes, I found a Melangyna lucifera in the Sonian forest by accident. This is the second record of Belgium and for me rather unexpected. In a sense it is clear that early spring species are not research well enough so it is always possible. Also the biology of this specie is unknown so who knows where we can find them.
I went actually on a mission to find M.barbifrons which horribly failed unfortunately. Instead I found a lot of Melangyna quadrimaculata and a few Melangyna lasiophtalma.
I wanted to take a couple of male M.quadrimaculata photo's with my phone to check if it is worthwhile to even take Syrphid photo's with my phone. I am sure if I knew this was a Melangyna lucifera I would have reacted differently! On the other end there is a wild photo of the specie now... still I advice you catch all Melangyna's directly as you see them and check them as looking from a distance could lead to wrong assumptions... I finally caught the specie you see in the photo and saw directly it was different.
As my phone camera does not produce high quality photo's you still can see it. On the left side you can see more or less the broad eye angle and on the right side you see the smaller spot on the second tergite.
One other thing I noticed is that the silver dust on the yellow spots which M.quadrimaculata has too can only be seen if you look to the abdomen in frontal view (anterior view). You have to play with the light a bit and the view angle though. But ones you hit it the yellow changes into a beautiful silver light.
Also I found compared to the article "Het zilveren elfje Melangyna lucifera nieuw voor nederland en belgië (diptera: syrphidae)" from Elias de Bree, Frank van de Meutter & Jonas Mortelmans that the yellow colour is less orange in my specie than the photo in the article suggest. It might the print/screen quality but it is good to know.
