Limnephilus decipiens, a northern caddisfly

We were out for a dog walk at RSPB Ouse Fen (VC29) on a bright, sunny day. There various birds around, including Marsh Harriers, Kestrels, Reed Buntings, Bearded Reedlings, a Green Sandpiper, Wigeon, Tufted Duck, and the first winter thrushes we’ve seen this season (flock of Fieldfare).
This fellow sitting on the gate sneck caught my eye too, Limnephilus decipiens, one of the many northern caddisflies. I only had my 150-600 mm zoom, so had to lean against the barbed wire about 3 m along from the gate to get the shot, hence the very short depth of field.
