I find that they don't squash, no matter how hard you hit them they fall to the ground, shake their heads and stagger around for a minute or two then fly off in search of more blood. Hard or what!

In defense of tabanids.
Why would you want to squash it? It's a non-blood-feeding male. I can appreciate squashing those murderous spiky tachs.

The first one is a male of pluvialis / subcylindrica.

The second one is more difficult, from the pic it might be crassicornis, however, time of year suggests otherwise.
I would need more/better pictures of the antenna

Thanks Theo, and I give way to your vastly greater knowledge. Now, I'm just wondering where I went wrong with the key in Stubbs & Drake:

I can't see any orange on antennal seg. 3; and there doesn't appear to be any orange at the side of tergite 2 and 3. So, following the key this must be either crassicornis or italica.

here's an enlarged photo of head/antenna - probably not detailed enough though.

And here's the only shot I got of the dorsal side - strong wind so very shaky.

Thanks

espace interoculaire=spac
e between eyes, thus frons including orbits. 2nd translation is OK.

21.08.14 15:51
Help again for 2 French words pls espace interlocaire - orbit? ecorces des arbres - bark of the tree? Thx

so looking at another eg Wangen (Parafacialia) 1.5 – bis 1.75 mals so breit wie das 3. Fühlerglied = Parafacialia 1.5 to 1.75 times as broad as the 3rd antennal segment (postpedicel)

14.08.14 15:26
You read my mind - I was wondering about that too

11.08.14 19:03
And nouns in German always begin with a Capital letter, whatever their place ! That was further misleading ! Shock

11.08.14 15:26
Thank you Stephane - I thought that was a full stop! I wondered why there was a single word!

10.08.14 10:14
e.g : "Der Abstand der inneren Augenrander entspricht etwa der 4fachen Breite des 3. FĂĽhlerglied." (Distance between inner eyes margin about 4 times as broad as 3rd antennal segment)

10.08.14 09:53
Must be "...des 3. + [Name]." which means "of the 3rd [name]" ; the point after a number is the mark of ordinal numbers in German !
