Elisabeth, I don't think that attraction to the horse somehow compromise Nationally Notable species in the UK.
1. Males of H. borussica have no pd on t3, females have 1 pd below middle and 1 pd above middle.
2. H. parva and H. glabricula have no spines on f3, only 2-3 av setae near apex.
3. it an error. Should be:
"12. t3 with 2(3) a-av and with 2(3) v setae (sometimes
look like pvv, but never as true pv). tar1-4 without
remarkable setulae. Azelia-patterns on abdomen
absent. f2 with 1 ventral spine .... aterrima Meigen.
– t3 with a complete rows of 9-10 strong av, 8-10 fine
pv and 7-8 fine shorter v setae. tar1-4 with 2 long
(2-2.5x as long as tar1-4 width) pointed d setulae.
Azelia-patterns on abdomen indistinct. Azelia-patterns
on abdomen absent. f2 with normally with 2
ventral spines .............................. gibbera Meigen."
4. I deal with imago only. Any questions about preimaginal
