Can anyone say if this big, showy female Tipulid is Dictenidia bimaculata or Ctenophora elegans, or something similar. Abdominal markings look more like the former, head marking more like latter, but no doubt the wing veins / marks are more definitive and I don't have a key. Both of these are quite scarce in the UK I believe, but it could be something else!. c18mm Wiltshire garden 11.6.10 nick upton attached the following image:  [157.46Kb] Edited by nick upton on 11-06-2010 17:33 Nick Upton - naturalist and photographer |

Looks just like one I photographed a few days ago (see barnsleywildlife). Ctenophora pectinicornis. |

OK, many thanks. Yes, sorry, I meant to put C. pectinicornis not elegans as one of my options and have read since that D. bimaculata has 2 black spots on the wings (as its name suggests) so C. pectinicornis looks right unless anyone says not! Seems to considered widespread but scarce in the UK, associated with dead wood eg beech. We have a huge beech tree nearby...

Very true... All replies are welcome (well usually anyway...) but some are more definitive than others!
