Recently I reared a female Scaeva pyrastri from the egg that I saw being laid. The female turned out to be melanistic. So I was curious to know more about this phenomenon in Syrphidae and I'm here asking if someone can send me a pdf file of the following paper:

Knutson, L.V. 1971. Melanism, Ring-segments and Associated Abnormalities in Female Hover Flies (Diptera: Syrphidae). Journal of the New York Entomological Society 79 (4): 201‒209.

Thank you!
