A Survey for the Caddis Limnephilus tauricus on Cors Erddreiniog, Anglesey (2016)
A survey of Cors Erddreiniog National Nature Reserve (NNR) from July to September 2016 failed to find the caddis Limnephilus tauricus (classified as Vulnerable in the UK) at its only Welsh locality. First found on the reserve in 2006 in a small area of permanently wet, gently-flowing, spring-fed fen supporting an extensive bed of Yellow Flag Iris pseudacorus, small numbers of adults were also found at the same station in 2007 and 2008. No larvae have been found to date. Wider searches of apparently suitable habitat on Cors Erddreiniog in 2008 and 2016 proved fruitless. Whilst the vegetation at the original station looked very similar to the situation in 2006-08, the water flowing through the site was less clear and appeared to contain more iron flocculence. Further searches of Cors Erddreiniog NNR are required to determine the current status of Limnephilus tauricus.
