Thanks for the ID and

Thanks for the ID and confirmation, with the antennae segments is this scape, pedicel and flagomeres together = 14!

Tipula paludosa

The three similar species in this group are Tipula paludosa, Tipula oleracea and Tipula subcunctans. If you have a female, with a long ovipositor as shown in this observation, then the easiest way of picking out T. paludosa is that the wings, when held back along the body, do not extend as far as the tip of the abdomen, whereas in the other two species the wings extend just beyond the ovipositor.

T. paludosa does have 14 segments to its antennae (including the scape, pedical and flagellum), but the segment at the end is quite small, and I'm not absolutely confident I can see it in these photos, although on balance I think it probably is there. The other two species have 13 segments.

The other useful feature is the gap between the eyes on the underside of the head - not the easiest thing to see on a live specimen! T. oleracea has a much narrower gap than the other two species.

I'm not aware of any difference in the length of the genitalia between these species, females of all three have a long ovipositor.

So I think this is most likely T. paludosa as Chris says, but a photo showing the full length of the wings and body would help confirm it.

Thanks for the detailed

Thanks for the detailed comments

I have added a final photo showing the wings, this may help with a final confirmation

ID Comment

Hi, thanks for posting the fourth and probably definitive photograph. I have got my ruler out and the wings are shorter than the length of the abdomen. I think therefore that this confirms the sighting as Tipula paludosa.

Martin are you in agreement ?

agree

Yes, I think that extra photo confirms it as paludosa, glad we've been able to resolve this one.
