Hello,

These diptera were always standing on top of the head of animals standing in water.

September 2015, Pantanal, Mato grosso, Brazil.

Here it was standing on Caiman's head, but could be on Jabiru's head (etc.), bothering those birds.


It seemed to be comon flies at the time ...

May be some kind of Tabanidae ?

They are female Tabanidae; males have larger eyes and do not bite.

From these pictures, I could not say more (I won't say: get a closeup !).

There is actually an article from 2002 on Tabanidae feeding on crocs in the Amazons.
http://www.scielo.br/pdf/mioc/v97n1/4360.pdf
Four species are mentioned there.

It is not Tabanus and it does not look like Stenotabanus.

So possible match would be Phaetabanus nigriflavus.

I know the genus, not the species. Genus could be a match indeed and nigriflavus would not be a bad name for this species.

I have seen this species and I agree Theo's ID looks correct but a closer shot would be great. Thanks for recording this interesting interaction!

Thanks a lot !! Wink

Closer shot wouldn't add information : it is hand shot at 600 mm with a 150-600 mm Tamron in a moving pirogue under schrubs ... No way (for me) to get sharper ... Cool
