New Zealand tree-fern muncher comes to Banstead
Meet Musotima nitidalis, a pyralid moth that should, by rights, be chomping on tree-ferns in Australia and New Zealand. But in 2009 a single was recorded in Dorset, no doubt having hitched a lift on a potted tree-fern. Since then others have appeared, mostly in Dorset, Hampshire and Sussex, but also in Essex, London and Surrey. It seems to have established a toe-hold, yet another adventive species that has happily used human intervention to colonise new parts of the world. Last night I had my first - the individual above - to the garden MV here in Banstead. Quite a striking moth, certainly one that doesn't need a degree to identify correctly.
