Do you think this is antenna damage, or are the unequal antenna caused by something else? Biting midge, Austin, Texas, USA.

(Ceratopogonidae). It appears to have a developmental problem. It's a female, and the right antenna is the normal size, but the left one is reduced for some reason. Males have much bushier antennae, so it's not a gynandromorph.

Yeah, that's what I suggested on FB, although I didn't know the iD of the fly. I suggested a male looks more like this, but I don't know if this is the same species or not.
... also photographed at the same location but a different date.

Yes, that looks like a male bipunctata
