Picture 2

M. domestica I think. The abdomen has no reddish hues. Also the size of frontalia seems to point M. domestica

---

In Musca domestica, the frontal vitta should be not less than three times as broad as one fronto-orbital plate. Here, it is clearly narrower, at most two times as broad as a fo plate.
Females M. autumnalis have usually a darker abdomen than males, often completely grey.
This female is either M. autumnalis, or M. larvipara.

---

I used to think even females M. autumnalis had reddish abdomen! :| Maybe this is a M. larvipara as you advanced...

---

Can we say, that the differents between M.autumnalis and M.larvipara is manly the lenght of the black hairs on the suprasquamal ridge ....
M.autumnalis = whit a group of black hairs
M.larvipara = black hairs on whole lenght

(Beside the differents of the lenght of the two flies...M.autumnalis 4,5-7,8 mm and M.larvipara 6-9 mm and M.larvipara is never spotted in the Netherlands)

And if so....are there not many mistakes between those two flies.


And Klaas...I have never heard of Musca sorbens...???

Only curious....JokeB)

---

I don't personnaly know M. larvipara, I always have found only M. autumnalis.
Another diffrence is that M. larvipara (like its name implies) is larviparous.
Musca sorbens is found in mediterranean area in Europe (Nikita has placed many pictures in the gallery). Musca sorbens has a typical pattern on scutum (2 broad black vittae forked in front of the suture).

---

Sorry...indeed in the gallery..;)
But I could not find it in my Key, so I wil make a notice..
And hope to find someday a M.larvipara!

Thanks Joke
