Hello,
Here is a fly encountered in the mid-mountains, resting on a rock.
According to its wing venation and the 4 post-sutural dc setae, it should be a Muscidae.
It could be a Thrichops, one of the mountain Muscidae.
We do not see a PD setae on tibia 3, but it could be hidden among the other setae.
What do you think please?
