About 16mm body very long antennae,creamy brown mottled colour,a single bluish spot on bottom of wing.
No interactions present.
Thanks for showing the pic -
A sure sign that warmer weather is arriving.
I do not think this is lunatus as it does not have a good lunar mark at the end of the wing and lunatus does not usually have such a prominent back stigma mark. This group of caddis are quite variable so I cannot be sure but would probably plump for Limnephilus decipiens, but L. binotatus is also a possibility.
