Wasp? No!

Whilst emptying some bits in one of the wheelie bins I noticed what, at first glance, I thought was a tiny wasp. It wasn't moving so I assumed it had recently died and collected it to put under my LCD Microscope. Read about that here
The wasp like insect was quite small at about 10mm long.



Oh-ho ... what is that extra part jutting out near the lower eye?



Let's turn the insect over and take a closer look ....



That looks to me like the type of proboscis used to puncture skin and have a free drink of my blood. Pretty sure that what I have here is a mosquito though so far I haven't been able to identify which species it is. Any ideas??
