Today I saw the weirdest and brightest fly ever and I am so desperate to know if anyone has seen one and if they know what it is.
It was just over 1cm long with a really bright turquoise thorax. But its abdomen was an irridescant cerise/pink! It was so colourful that I watched it for ages until it flew away. The way it moved its very long pink abdomen reminded me of a wasp with its stinger, but it was such a thin little thing that I don't think it was any type of weird wasp etc (if i had thought it was, i would not have been so close to it for so long!)
It was probably only 2-3 mm wide, so I am wondering if it really was a true fly or not? It certainly flew well enough!
It made no sound that was audible from 1-2 metres, so I don't think it can be anything other than maybe a rare mosquito-type fly?
It has certainly got me massively puzzled, and I would love to know if anyone has any ideas as to what it might be.
Thanks in advance,
Could it have been something like the fly in the image here: http://flickriver.com/photos/ricosz/5375116887/? They are soldierflies of the genus Sargus and, depending on age, lighting, etc. they can have different bright metallic colours.
I don't think so.
The one in the picture appears to have spots of differing colours on it....... this one was PURE turquoise and PURE irridescant pink....... there were no other markings visible.
I was lucky enough to get a good look for a few minutes, and the vivid colouration covered the entire body parts mentioned.
I viewed it in sunlight by the way.
I have to admit to not looking at the head - i was so taken by the colouration on the body, and the head just appeared plain (was probably black or I would have noticed something).
Would LOVE to know more if you have any other ideas,
Hi again Paul.
The SHAPE of the fly is PERFECT........ so maybe it COULD be a variant?
Hi again Paul.
If the colouration and pattern of the colours is totally variable, then it is certainly a possibility.
I have had another look at the photo, and it very much represents the shape of the fly to the max.
Do you know anything more about these? Are they common in UK? Do they sting etc? This one had a bright pink waving abdomen that would put me off getting too close!
I am so happy to have found someone so knowledgeable - that little fly had me buzzing all day!
I would LOVE to know more about them if you have any links etc, and would love to know other UK sightings (I am in Bedfordshire).
Many thanks again,
Sounds like a Ruby-tailed wasp to me - Hymenoptera: Chrysididae.
They are notoriously difficult to id, but Chrysis ignata is one of the more common species and looks like this: http://bwars.com/Chrysis_ignita_agg.htm
What do you reckon?
YES YES YES!
That is it!!!!! BRILLIANT - thank you!
Are they new to UK? Do you know much about them?
That is EXACTLY the colouration (mine was a bit thinner though)
You're a STAR!
They are a common and widespread species seen between April and September. There are many species of Ruby-Tailed Wasps and they all parisitize other bees and wasps (mainly Mason Bees) for this reason they are sometimes called Cuckoo Wasps. And their stings are not functional so it cannot sting you.
