Hi,
This fly, less than 5 mm in size, hatched from a small pupa (Lepidoptera). Is ID possible?

Hi Marion, it's a difficult one - for me, not all significant features are visible. But I suspect it could be an Elodia morio.

---

Hi Eric,
thank you very much.
I can try to take more photos. Which key features should be visible for the confirmation of Elodia morio?
Greetings, Marion

---

Hi Marion, photos of the apical bristles of the scutellum and the ocellar bristles with the oi should help.

---

Hi Eric,
here is another new photo. Photographing black flies without laboratory equipment is a real challenge.

Greetings,
Marion

Hi Marion, I know the problems of photographing black flies - your photo is nearly perfect!
With the T&H key + translation by Rayner & Raper I think we see this:
ocellar bristles ≈ oi [not sure]
2nd arista segment > diameter
scutellum with apical bristles [but thin enough?]
2+3 dc
r-m almost vertical on m
r-m to m-cu ≈ m-cu to bow
mid tibia: 1 ad
abdomen shiny black, without bands of dusting
tergites 3 & 4 with discals
+ hatched from a small Lepidoptera pupa

But I think it's wise to wait for the expert.

Hi Eric,
thank you very much for the summary of features.
As you suggest, I`ll wait for the expert.

Pictures of the host are in the lepiforum.

I have seen Elodia morio only once, it seems this looks like one, if we are really sure the topcel is open.
Elodia is more often reared than seen in the wild, so that figures.
