Hi, everybody
I found this Stratiomyidae resting on Stinging Nettle leaves in Cangas de Onís area (Asturias, N Spain), on April the 27th. I suspect it can be Microchrysa polita but I'm not sure. :(

¿Can it be confirmed through these pictures? I couldn't get better shots.

Many thanks for any help!!

Hi Marian. I came across this post while checking the ID of a Microchrysa. I'm not an expert, but I believe that M polita has black antennae and black femur with paler knees. On that basis, your photos do indeed look like M polita, to me at least!

Best wishes,
Martin

Marian,

Besides the fact that there is no alternative in Spain!

Un abrazo!!

Why should M. cyaneiventris not be able to occur in Spain?

Ruud,

I wasn't counting with that possibility. :S But I thought that this species had yellow antennae and largely yellow legs.

Sorry, cyaneiventris back in the race!

Bedankt Ruud!

Saludos!
André

Hi everybody! :)

First of all, thank you for your comments. :) Sorry for the late reply but I didn't get notifications of your answers (maybe my fault, if I didn't click the box to get them? :( I thought I had!)

Yes, André, I'm VERY interested in Stratiomyidae and I'm working with the keys. ;) But as I'm starting I lack confindence in myself and I prefer to check with experts my conclusions. ;)

In this case this one didn't look to me like Microcrysa cyaneiventris (by colour of legs and antenae, as Martin and André pointed), my main doubt was if it could belong to other genus that passed overlooked to me. But it seems I can consider Microcrysa polita quite distinctive and I hope I will not doubt next time. ;)

Thank you again to all of you!! |t

Regards

Surely polita male. You can exclude cyaneiventris when you see abdomen with many metallic reflections, like here.
