From January 2015, attracted to a "moth-wall" in the evening.

Probably Chlorotabanus. They are active at dusk; the North American species is named C. crepuscularis after its flight time.

Many very similar species, according tot a recent review.

Chlorotabanus never have a dorsal projection on the basal flagellomere complex on the antenna.

This is Rhabdotylus sp. (sometimes put as a subgenus of Stibasoma). Cryptotylus is also very similar but I'm pretty sure it's not that. Females are much easier to identify because the frontal callus is very different in those genera.
