I was astonished when I saw this picture taken by my friend Francisco Rodriguez. It looks like Ibisia vaillanti to me. As far as I know there are only two species of Ibisia cited in Spain: marginata and vaillanti. Females are not separable by pictures but males of I. vaillanti are supposed to have much darker wings overall than marginata, specially in the basal and apical areas. Have a look at this article: http://www.limnol...49a2a202a6 the drawing of the wing of I. vaillanti looks exactly like the male specimen my friend photographed, and certainly is much darker in the main areas than any of the pictures of marginata males I have seen. I would like some opinion as I have no experience with these, only theory  It might not even be Ibisia, but I think it is.The picture was taken by a river in Ragol, Almeria, SE Spain on the 4th June 2012.

It is possible, but the intensity of the markings in available images of Ibisia seems to be quite variable so I would not put too much trust on these. The markings on the abdomen, though, are different from what I have seen on most specimens identified as marginata so it probably is another species. However, see my remark HERE.

Thanks a lot for your reply, Paul  I would have been very happy with a confirmation but just an opinion from someone makes me have a more real perspective on these which is good enough  |
