Calliphora vicina (?) and issue with flying.

Hi,

I've recently found a little animal on the (clean) toilet bowl water, nearly drawning. I've rescued it with a piece of paper and put it on a paper sheet. Since it seemed unable to move normally, i used some toilet paper to take away the remaining water, and it seemed to work.

I suddenly recognized it's of the diptera kind, but it isn't a common housefly, it has some black silks on it and a dark/blue bottom. I'm keeping it and trying to feed it, and it works. I hadn't seen it before in my house so i don't know if it could, but at the moment and since its rescue it cannot fly.

I try to attach some image at identification purpose:

I know this is mostly an identification and study forum, but since i'm getting very interested in this little animal, i would really like to know if i've at least guessed its kind (my doubts are between calliphora vomitoria and calliphora vicina).

Moreover, is there in these pictures any evident issue that makes it unable to fly and consequently any way to rescue its flight?

Some days ago it used to climb a bit better than now (or at least it had more strenght), i've checked for the wings and they don't present any apparent fault... The animal always tries to leap or to jump backwards, like to take flight but it doesn't work... Any way to help it?

Thank you in advance for your kind answers and if i'm off topic (it's the first time i land on this forum) please, forgive me and if you can, be so kind to move the topic in the right section.

Thanks

Re: Calliphora vicina (?) and issue with flying.

It does appear to be a Calliphora species, though I can't quite tell from the photos which species it is.
The right wing at least has not developed properly, which would explain why it's unable to fly. You can keep it alive by feeding it a sugar solution. It is a male, so if you can find a lady bluebottle for it, it may still be able to pass on its genes!

Re: Calliphora vicina (?) and issue with flying.

Thank you for your prompt and accurate answer! It seems this little insect has also some balance problem, because it keeps turning on its back... Nevertheless it feeds from itself: apples, prunes, some banana i've tried too but it refused it... Do you think that in this state of things the sugar solution is still necessary to keep it alive or better to let it feed from itself?
About the idea of making it mate, i've seen one similar insect flying at home (it's bigger, so probably a lady?) if i manage i let them in one and the same place and see what happens!

Thank you for everything!
