> > New mayfly from Spain: now, a nymph

IsidroMarch 18th, 2008, 1:34 am
Posts: 24Im' not hoping an ID, due to the "success" of the last post of European mayflies. I suppose that if t's almost impossible identify mayflies by photo at adult phases, much more difficult will be at nymphal phases. But, maybe someone know, at least, the family of this one. This nymph was caught at Ebro river, in Zaragoza, NE Spain. This river is great and deep, slow and highly contaminated, with lime. The nymph sizes about 15 mm (without cerci). Can be identified, at least, at family level?



Many thanks.

Isidro-

Your mayfly nymph appears to be a clinger of family Heptageniidae, perhaps of genus Ecdyonurus. Given a decent macro photo, identifying mayflies to family and genus is actually somewhat easier with nymphs than with the winged lifestages, as the gross features on the nymphal lifestage are much more distinctive.
Best regards,

Posts: 24Many thanks Taxon! This is very surprising for me. I hoped that teh adults would be much more easily identified than nymphs. The picture is not good but my camera don't give more. Thanks again for de ID.
