These were found on Burdock.



Any help greatly appreciated, JohnB

Given the angle its a bit difficult to say, but they do have the basic jizz of Terellia tussilagensis, one of three (IIRC) with Burdock as a food plant.

I'd agree with that, I've had the female and yesterday got a male.. need to keep my eyes peeled for a mating!

Thanks Gerry.

I have just processed a couple more images which were on the same Burdock plant so hopefully the same.

Yes, this looks right for T. tussalaginis.

The dorsal shots make it much easier to check the wing pattern, and there's enough of the chetotaxy (hairs & setae) for confirmation purposes. Plus it matches well with photos I took a week ago and checked against the keys.

At this time of year this fly can be found on most burdock heads. Oddly, although I now know how to find the larvae/pupae of Tephritis bardanae in the flower-heads of Burdock, I've never seen the adult fly.

Thanks for the confirmation. Maybe next time I will need to look out for T. bardanae ;-)
