Outdoor carpet

Common Carpet (Epirrhoe alternata)
For those who think that all moths are boring little brown jobs, I present proof that this is not always the case. This Common Carpet (Epirrhoe alternata) flashed up in front of me the other day as I walked the garden paths, and eventually settled back into the grass where I could photograph it. Yes, it's brown – and black and cream and grey and rust – but how about that patterning?! Gorgeous. And very good at breaking up the outline of the moth. This is a common and widespread insect across the whole of the UK, even in many of the offshore islands. It's found in a remarkable range of habitats: woodland, moorland, some grasslands, heath, fens and marshes as well as urban areas and gardens. Those of us in the south see them from May through Octocober (as many as three separate generations!) while those in the far north of Scotland typically only get them in June and July. The one broad dark band across the midwing (often with a grey component), the single sizable "point" at the back edge of that band and the thin grey line that runs through the white stripe just beyond that point all help to separate this species from a few supeficially similar ones. As with all UK moths, the adults are nectar feeders. They visit flowers primarily at night, though they often begin feeding at dusk. Common Ragwort is a favourite, and we have plenty of that, so our visitor should be happy here. The larvae feed on various species of bedstraw, including Common Cleavers – another thing we have plenty of – so any potential offspring should be provided for as well.
