I've just found two different athericid/rhagionid in the same shrub! They was consecutive photos!

2nd July 2011.
Arnes, Castellon, east Spain. Mediterranean montane forest (dense Pinus halepensis qith some Quercus ilex, Arbutus unedo, Pistacia lentiscus and terebinthus, Smilax aspera, etc). Over the water of a crystalline river, in a strawberry tree (Arbutus unedo) in shady zone.

Both are Athericidae.


First is Ibisia marginata.

For second I do not see R4 vein well - it is out of focus! But it seems follow a path non-sinusoidal . It can be an Atrichops. Different sex compring ones with the Andrade. I would say Atrichops (yours a female). It fits well: broadly darkened tip and smaller areas infuscated in the wing; alternate band of yellow/black in abdomen; R4 vein seems to follow a non-sinusoidal path (in this case it NEVER could be an Ibisia or Atherix)

The two last are Ibisia marginata (photos are rather dark).

I'm pretty sure your photo img713.imageshack.us/img713/727/imgp1705g.jpg - shows a female of Atrichops crassipes. R4 is gradually arched, so never could be neither Atherix or Ibisia. See the other reasons forementioned for this ID. Yours is a female, and the Andrade's Atrichops is a male.
Larvae of this species are quite sensitive to water pollution. They need very well oxygenated and crystalline waters.
