Tephritid

This is a male and it's probably waiting for a female (with a long cone shaped ovipositor) to mate with, as many species use thistle and knapweed buds to mate on and lay their eggs in. To be sure of species needs really close up views, but some are host specific. Do you know which thistle this is?

Thistle

shows what I know eh, I thought thistles were thistles I didn't know there were different types. I can't actually remember where I took this apart from it was on the meadow. I take pictures of all sorts of things. I am sorry I can't help you there. All the thistles looked the same, they start off on the ground almost fluffy apearing to be covered with fur, then they start to grow taller, some about 3 feet tall and they all seemed to be purple. on't know if that is any help.

Which thistle

I think there are around 20 UK thistle species and a lot do look very similar! I THINK this one is Creeping thistle, Cirsium arvense, based on the look of the flower buds and the white lines in the elavs, and the height is about right. A few species of Tephritidae seem to use this species, but the one that looks closest is
Xyphosia miliaria which I think this is based on wing markings and eye colour: see http://www.eakringbirds.com/eakringbirds4/insectinfocusxyphosiamiliaria.htm Maybe a real expert can confirm if I adjust the ID.
