Hello,
is this 6-7mm tephritid from july in austria Xyphosia miliaria? It seemed to be very interested on this Centaurea-bud, but I always thought they like Cirsium and perhaps Arctium.
Thanks,
Michael

It is.

I find them also in numbers on
Tanacetum vulgare in late summer. That does not mean, they are breeding at it.

Yes, you are of course right. I just hoped to have found something more interesting ;-)
Greetings,

Tephritid females sometimes observe different plants for a suitable oviposition substrate, but normally they do it for feeding, like honey dew (Centaurea scabiosa in this instance) or open nectaria (on Daucus carota)
