Large caddisfly
I set the moth trap at Cadoxton Ponds last night and had the biggest caddisfly i've ever seen in the trap this morning.
Apologies for the poor photo but is it possible to id it as Phryangea bipunctata?
I think bipunctata usually has a gap in the dark streak, whereas grandis doesn't, but the RES key urges caution and checking of the tip of the abdomen. P. grandis is apparently the less common of the two in Wales.
Comparison with images on NatureSpot this looks more like a female Phryganea grandis.
ReplyDeleteThanks Howard, i think you're right
ReplyDeleteIt is certainly one of the two, but I don't think separating them is that simple a matter though - I'll check in the key when I get a chance.
