Hello,

on ivy in our garden (northwest Germany). I can't even propose a family. For Limoniidae it seemed very small with its 4.5 mm.

Tipulidae s. lat. can be very small. Quoting the guide to Tipulidae in Manual of Nearctic Diptera:

Length up to 60 mm; size varying from tiny species of Tasiocera Skuse with wing length of about 2 mm, to large species of Holorusia Loew with wing often 40 mm long and of Leptotarsus Guérin-Méneville (Longurio Loew) with body length often 60 mm.

Hello John,

many thanks for your interesting comment. The smallest Limoniidae I knew from here were about 6-7 mm. The largest Tipulids were a Tanyptera atrata female with at least 30 mm body length (including ovipositor) and - of course - several Tipula maxima.

And what would you say about Dicranoyia (Melanolimonia)?

D morio?

there are many Limoniidae around in our garden these days, which I think are Dicranomyia (posting is from 2014, but they are also present now). But those are bigger (8-10 mm) and often greenish. I did not know D. morio, yet, but pics I found in the net, lool rather similar, thanks!

Actually i have no doubt on the subgenus, and it is a really small specie, even compare with D chorea ;)

Hi,

I have a slightly better (wing venation visible) picture from yesterday.

And the other Dicranomyias, the bigger (10 mm), greenish ones, are sitting next to it at the wintergarden, trembling constantly with high frequency for hours and hours... :D
