Shortly after taking my seat on the Cardiff-Swansea train this morning I noticed a small colourful micro fluttering around me. Fortunately I had a pot in my rucksack and the lady sat opposite was too engrossed in her book to notice me searching for the moth beneath the table. Luckily it had alighted on my rucksack and was easy to pot.
The moth seems to be Denisia albimaculea, which, according to my version of the county database, hasn't been recorded in VC41 (or Wales?) since a 1934 record by Hallett from central Cardiff which is regarded as questionable.
The question is - what was the origin of the moth? The train had come from Crewe, and the moth could potentially have hopped aboard on the way, but I think it's more likely it landed on me as I cycled through Bute Park to the station, as it was flying around me as I took off my ruscksack on the train. What do you think Dave - can I count it as a Glamorgan record?? I'm going to have a look on lime trunks (the larval foodplant) in Bute Park tomorrow if the weather's ok.
I don't think it's the similar (but rarer) D augustella, but have kept the specimen just in case.
