The Wood Swift is found throughout Europe. The male 

 expands from one inch to one inch and a quarter, and the 

 female from one inch and a quarter to one inch and three- 

 quarters. 



The head, antennae, and thorax, as well as the fore-wings, 

 are in the male reddish-yellow, yellowish-brown, or more rarely 

 brick-red. A whitish, sinuous line extends from the base of 

 the fore-wings to the inner margin, and another similar line, 

 bordered on its inner side with dark brown, runs from the 

 apex to the inner margin close to the first. In the middle of 

 the wing is a dark brown spot bounded with white below. 

 Beyond the outer line is a series of small dark brown spots, 

 and in front of the fringes, which are reddish, is a row of dark- 

 brown lunules, with the concavity directed outwards. The 

 hind wings are ashy grey (rarely uniform reddish-yellow), varied

 abdomen is yellowish-grey, with a brownish anal tuft. The 

 under side is yellowish-grey, shaded with blackish in the
