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

Sometimes search bots cause heavy traffic, on occasion the site is being swapped by server requests, probably hackers trying to find an entry point to hack the server.
