Hoverfly

Lovely pictures - do you think it might be laying eggs into the stem of the plant?

Dead

It is presumably dead and is very much in the position flies adopt when infected by an Entomophthora fungus, though there does not seem to be any sign of that.

It does not look unnaturally bright to me, but maybe in real life it did? The colours in the first picture are what I expect to see in the species.

colours at end of abdomen

so the multi-coloured stuff at the bottom is stomach contents or something? Even so, how come such bright yellow & red? pollen, perhaps

Multi-coloured stuff

I assumed that was the male genitalia which have hinged out. Sorry...red is a colour I struggle to pick out, so I had not seen that! I am not sure why it would be that colour. The yellow does look like pollen, though.

Odd colours

i think there is a reddish midge below the dead hoverfly's tail and to the right, also apparently dead.

There is apparently yellow pollen spattered over the rear tail of the hoverfly, but I wonder whether something has taken a chunk out of the lower tail, removed some of the abdominal contents and killed the hoverfly. I can't see any fungal attack, but maybe the fly had adopted the "attitude" anyway. Or maybe the fungus has started its infection, and just is not visible yet.

Quite a lot of this fungal attack in the wood near me at the moment.
