Making up a quite mixed bag in the moth trap this weekend, there were a handful of caddis flies of two different species. On the right the “half-moon” caddis fly (Limnephilus lunatus, #686), with a dark-rimmed pale semicircle at the tip of its wings. This is a species often coming to light at night, which I’ve caught several times from late summer through to now. The darker caddis fly on the left is a new species, Anabolia nervosa (#708), which also flies from August to October. The larvae of this caddis are usually found in streams, where they make a case of sand particles and small twigs.
