. The Fiery Clear-wing is found in Western and Southern 

 Europe. It is rare and local in England, but is met with 

 occasionally near Folkestone. It expands three-quarters of an 

 inch, or a little more. 



The body is blue-black, with a yellowish-white front and 

 collar ; the thorax has a white spot on each side at the base 

 of the wings, and the abdomen has two white belts, one on the 

 fifth, and the other on the terminal segment. The anal tuft is 

 black. The borders, the nervures, and a cross mark in the 

 middle of the fore-wings are black. A triangular area between 

 the base and the central mark, and a rounded space beyond it, 

 are clear and transparent, the rest of the surface being bright 

 orange-red. The hind-wings are transparent, with a minute black 

 spot bordered with red in the middle of the costa. 



The larva is said to live in the roots of Rumex crispus, 

 Artemisia campestris^ and Elychrysum.
