We have only one species previously recorded in Shetland which is Siphona geniculata. Don't know if this is it...in my garden this morning.

Sorry for poor photo's....windy and damp day up here today :|.

Siphona sp. maybe a species can be possible... but don't trust this because virtually almost all Siphona are no-ID species by photo...

It seems to be either geniculata or cristata.
I don't think you have broadleaved trees on the Shetlands, do you ?

Thanks Jorge & Theo, I punched Syphona into the Forum Search facility...seems they are impossible to ID, or as Theo put in one of his replies.." Siphona don't know which one, is the most common species".
Theo, what are trees? We have Family Trees. But seriously, we have some Sycamores scattered about the Island (got 2 small ones in my garden) but that's about all I can think of...Too windy for trees up here (salty wind) :|.

In southern England the commonest Siphona is geniculata, followed by cristata and maculata. But in Scotland it is much harder to predict via probability because up there we have records for all the really nice, rare ones ;)

Hi Chris....for Shetland to be lumped in with Scotland grates to the extreme, even if you only meant so geographically. A bit like me saying Reading is part of France...

cristata is known from Geometrids on broadleaved trees, so that is a bit difficult on the Shetlands.

Geniculata is well known from Tipulidae larvae.
So given the biology, that is your candidate.
I do stress this is not an ID from picture.

In dutch, we have this family Geenidae, which would translate in English to the superfamily Noidea
Very common, many Siphona belong here.

Would that be the Superfamily NO IDEA Theo...I am well acquainted with that.....My name is Roger...NOT Uwe :P Afaik

Need to get up a bit earlier in the morning to catch me out :D. Nice to see a Dutchman with a sense of humour...Sorry Andre

Yes, you got it. I was actually very pleased to find this dutch joke so easy to translate.

But remember: Noidea is just a junior synonym of Geenidae
