Crane-fly, but which?

Description:

This seems more striking than the crane-flies I am used to seeing and I would like to know if it is a common crane-fly, or maybe Tipula maxima?

swelling

The swelling at the end of the abdomen is the male's genitalia, which in Tipula cava and a few of its relatives is large and bright orange! Of these large orange craneflies T. cava is the one I see most frequently, but there are several similar species and a clear close-up photo of the tip of the abdomen is needed to confirm them.

Thanks

Many thanks for the ID and the detailed information. Tipula cava is not listed in my Collins insect guide - must find a more comprehensive book! If I see one again when I have my camera I will now know what to aim for!
