Caddisfly drawn to light from Patio-door.

Thank you for the ID Cathal, out of my depth with these. Do they normally fly in winter?
According to the book they dont, this is a fairly prospective ID, I am no expert I just have a good book on them! I think it has been fooled into thinking it is Spring time by the mild weather?
The pale dorsal stripe is typical of both the Stenophylax but it is also there on the slightly smaller Micropterna sequax ("listed as Stenophylax sequax in Macan 1973").
What length would you say that forewing is? My 18mm guess reading might be a bit over?
Hi, from measuring the pic with a ruler, it comes out at 19mm,if point of attachment is taken from the start of that dark streak behind the eye to the apex of the wing tip.
We are close to a 'brook' & a ditch which can be silty, but also various sized gravels. There is also a nearby pond & surface run-off bunds. The R. Soar with the interweaving Grand Union Canal are less than a mile away. Gareth
I am just not happy there are good wing characters to tell vibex and permistus apart. I would tend more towards permistus. An interesting record that just might be a very late running male rather than a very early one. No-one tells them the females have all laid up and died.
