Yesterday I got my book about Tephritidae, and this was my first Tephritidae determined.
I'm accualy not really shure.. Thats why I ask it here Smile

Im not really shure it is Icterica westermanni (=Merzomyia westermanni), because I read it is a rare species in North-Belgium. But still, if anyone could confirm. Are there any Campioglossums similar?

Other info:
Found many animals on Senecio jacobaea (+-10 on 100 meters).
In Ostend (Belgium)
size of the wing: +-6mm from base to tip
date of catch: 14august. (so the animal is collected)

Many thanks, Jonas

surely Merzomyia westermanni. My reason to exclude this species from Icterica and to erect a separate genus was that the N American Icterica and the Olde World "I." westermanni and allied licenti Chen and mongolica Korneyev actually belong to a different tribe... So Merzomyia is the valid generic name.

BTW, it is not rare in the Netherlands: most of my specimens were collected there by Bob van Aartsen and John Smith. It is also present here in Ukraine, but only in the South East.

thank you very much.
I'm glad my first Tephritidae-determination was right. I will add the photo to the gallery.

Bye, Jonas

For Idiohelina, 3 Malloch's papers, Exotic Muscaridae III, XV, and XXXV

Species with mouth parts that appear to be 'similar', like Sargus, do feed on honeydew. I have never seen Hermetia in nature...

18.09.15 17:42
Thanks Paul, some sites report that it don't have functional mouth part, other sites say it feed nectar, some publications say it "probably" feed nectar and it's a pollinator.

18.09.15 11:57
Sounds like it might be. Do sites that 'say not' state that they do feed or don't they mention anything?

14.09.15 20:42
Question: is it true that the Hermetia illucens don't have functional mouth part? Some sites say yes and some other say not. It's a bit confused. Thanks Smile
