AT FIRST GLANCE you might think ‘butterfly’ as the Early Thorn, Selenia dentaria, is the only Thorn moth to hold its wings up in butterfly fashion.
You might be thinking that late July doesn’t qualify as ‘Early’ but this is a female of the second generation, which usually has a larger tawny orange patch on its underwing than the February to May generation.
As the name suggests, she might well be looking for a blackthorn or hawthorn to lay her eggs on, there are plenty in the immediate vicinity, but the larvae will also feed on birch, alder, honeysuckle, sallow or bog-myrtle. They’re common in a wide variety of habitats including gardens, hedges and woods so they should feel at home here.
