Hello Helge,

it is a Melinda species recognizable by the blue color and the bend of the m-vein.
the width of the frontal vitta and the apparent lack of a pre-sutural ia leads to a male Melinda viridicyanea.

Best wishes,
John

well, I Thank you for helping me with Syrphidae a few times before. I appreciate you and i'm happy to help you in turn.

I will add a photo of mine of a male M. gentilis just to illustrate the differences between viridicyanea and gentilis. I hope it is helpful to you.

Best wishes,
John

Hello Helge,

very nice drawings. I haven't seen this before. May i ask where you foud it?
I use Dr. Rognes material to learn about Calliphoridae. However, i discovered the difference in size of the frons by having male specimens of both species. I noticed the size difference immediately. I had to check the material of Dr. Rognes to see if he mentions it. He does mention it in his decription but i didn't read the description of gentilis until after i had identified it.

Anyway, i have documented male and female of viridicyanea and gentilis. The females also have a difference in size of the frons but it is much more difficult to judge in a photo.

Best wishes,
John

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
