As the spring and summer passes, week by week, so the most common moth in the trap changes and by August we are in to the willow beauty (Peribatodes rhomboidaria) season. This geometrid species is thought to be single brooded but flies from June through until the end of August and we may even get some in September too, so there may be a second brood some years.
At first sight they look very drab insects but on closer examination they have lovely brown and grey mottled wings and they justify being described with beauty in their name.
The willow beauty is widely distributed across the whole of the British Isles and is very common. They are readily attracted to light and can often come in to houses where there is a light on and a window open. Although named willow beauty it feeds on various plants and lays its eggs on a variety of trees including hawthorn, birch, privet, yew and plum as well as shrubby plants such as ivy and travellers joy.
