:| I know, it it is difficult to understand... I will try to explain it again.

While I was trying to identify these green and blue flies I found last year, I searched a lot in the internet. Once I read an article or something, where it was explained that in one species the males are (mainly?) blue(or green), while the females are (mainly?)green (or blue). The problem is that I don't remember if this article treated a calliphorid species or a muscid species. I am still searching for this article or this website.

is this easier to understand?B)
