28th of June 2024 I took a picture of a Pelophylax perezi (Iberian Water Frog) sitting i Río Majaceite near El Bosque in Andalucia, Spain. After taking the picture I noticed several dipterans sitting on the frog. Can they be identified? And what are they doing there? Feeding on skin exudates?
P.S. Yes there are only 5 flies in picture here, but the uncut version has 7 ;-)

I think they could be females
Atrichops crassipes.

Hi Eric
Thx for the interesting suggestion! I see that "Females of the genus are all known to feed on frogs (Nagatomi 1964)" - do you know in what manner (I do not have access to that paper)? Blood or skin exudates?
