Need somebody who knows a lot about insects ?

Question

Okay, so I have left my back door open and some fly's that have been recently been hanging around my bin have flown into the house. Isquattedd one and then picked it up with a piece of paper to throw it outside, but when I looked at it, it has a blue colored back and seems to have a stinger, (But i'm no expert). Is this just a regular fly or something else?

Answer 1

Is this your "fly".  The "stinger" on a wasp is a modified ovipositor.  Its purpose is egg laying(so any with a stinger is female) and is some wasps and bees it is modified to sting.  A fly always appears to have just a pair of 2 wings while a wasp has 2 pair of 4 wings.  Take a look at these wasps and see if one is yours.  If not type wasp into search for the site and it will give you many more.  Also you can click on any picture for more information.  A blue-black wasp.

Answer 2

Sounds like a blue blowfly.  I am attaching a link for a photo of a green blowfly (exactly the same but blue). No stinger though

Answer 3

Flies don't have stingers.  Wasp have stingers.  You might have a wasp nest in the bin.

It may be a bluebottle fly.  They seem to fit your description except for the "stinger."  Take a look here:
