Hello

I found today this gall on the stem of Artemisia vulgaris. It is the gall of Campiglossa misella. I am looking for information about the development of the larvae (both generations). Who can help me ?

Greetings Volker

Hi Volker,

Some info on the first generation as a gall-inducer has been cited after some early British sources by Ian M. White (1986) in his article and then repeated in his Keys to British Tephritidae (1988). Unfortunately, I am away from my tephritid library at tthe moment.

I guess your re-discovery of this gall is very interesting and deserving a short publication; however, I'd strongly suggest to add also pictures of reared adults, if possibly.

Sorry for the delay -- I was at that moment on a collecting trip out of Internet access.

In "Fruit Flies (Tephritidae): Phylogeny and Evolution of Behavior" it says, that Campiglossa misella larvae feed within galls formed by a gall midge.

Ben, thank you. And still unknown if this happens everywhere/ Again, for 35 years of my fruit fly (and in paticular Campiglossa) studies I was unable to find any galls like that on A. v. Strange, is it?

Strange indeed Valery,

Here in the Netherlands it's a common species. At the moment I see many Campiglossa misella together with C. producta and Dioxyna bidentis feeding on Asteraceae. I guess they are preparing themselves for the winter.
I saw a gall on Artemisia in 2009, and moreover, an adult Campiglossa sp was hanging around on the gall, but before I could take a picture he or she flew away.
