ID : Chironomidae species?

Hello,

Whilst processing a batch taken from Bickleigh (Mid Devon) yesterday, I had a distinctive chironomidae species and thought it worth popping on here asking if it was possible to identify it please?

Regards,
Andrew.

Probably Microtendipes pedellus

Re: ID : Chironomidae species?

Thanks Tony, would an image of the genitalia after clearing and slide mounting be more helpful?

Regards,
Andrew.

Yes, a nice clear image of the genitalia would be helpful, but I'm fairly confident that this is pedellus from its colour.

Thanks Tony, sorry for taking so long to get this done. I have attached an image which I hope will be sufficient to clinch it.

Regards,
Andrew.

That looks good for pedellus. I can see most of the diagnostic characters in your picture. If you can get a more strictly dorsal shot in future, particularly of the anal point, its shape is often used to distinguish species, but otherwise the clarity of the image is great.  smile

Brilliant, thanks Tony. That will be a nice one to add to the Devon records.

If you or any interested parties looking in want the details for this then they are 09/04/2017, Bickleigh, VC3, SS934077.
