About Me

My photo

I have been interested in nature for most of my life but since I retired I spend as much time as I can exploring the nature reserves and wildlife hotspots of my adopted home, Dorset in southern England. Whilst out I record what I see and take snaps where I can (I am no photographer!) and that forms the basis of my Nature of Dorset website. When I find something new I like to research it and write about it in my nature notes, it is how I learn and hopefully you might find my notes helpful as well!

This website is for the people of Dorset interested in wildlife and for people from elsewhere interested in the wildlife of Dorset!

Laothoe populi: the poplar hawk moth

The poplar hawk moth (Laothoe populi) is very different to in appearance to other moths (apart from the eyed hawk-moth which is very similar). The shape and wing formation is unique and the poplar hawk-moth cannot really be mistaken for anything else. It is widespread across the British isles and is quite common.
It is a big moth and if you see it fluttering around a light you could easily think at first that it was a bat. It must rank as one of Britain's largest insects I would have thought. It does vary in colour between this almost blue to a much lighter shade of brown. There is also a buff version found, notably, in the London area. These browner versions tend to be the females.
This is a moth readily attracted to light and is single brooded flying from May until July although in good years there can be a second brood in September here in the south. The food plants for the larvae are poplar, aspen, sallow and willow and it is the latter two of these that are common and would usually be the host plant in Dorset. The insect overwinters as a pupa.
