Phryganea grandis

6th June 2012, Wednesday


Caddisflies (Trichoptera) don’t often get a look-in on this site but this one’s a bit special, dwarfing most of the moths in my trap in Rye this morning. The pot lid is 5 cm (2 inches) across. There are nearly 200 British species and Phryganea grandis is the biggest – this is the larger female. Although they fly deceptively like moths, there are many differences such as hairs rather than scales on the wings, palps on the head and no proboscis for feeding. It’s on the Rye Harbour list but I don’t know how common or widespread this species is in Sussex.
