Lloyd's natural History 



The Oak Eggar is common throughout Europe and Northern 

 and Western Asia. The male expands about two inches and 

 a half, and the female about three inches. 



The male is of a deep chestnut-brown with an ochre-yellow 

 band running across all the wings beyond the middle. This 

 band is clearly defined on the inner side, but becomes hazy 

 externally, where it runs into and blends with chestnut-colour. 

 On the fore-wings is a small white, nearly triangular, central 

 spot placed in a dusky ring and a yellowish patch at the 



Oak Eggar. Female. 



base. The border of the fore-wings is narrow and brown, and 

 that of the hind wings is broad and ochreous, and occasionally 

 clouded with brown. The body is of the same colour as the 

 daik portion of the wings, and ochre-yellow beneath, and the 

 legs are also ochreous. The antennae are chestnut-brown. 



The female is generally larger than the male ; the markings 

 are similar, but the body and wings are ochre-yellow, with the 

 central band paler, and the white spot on the fore-wings larger 

 than in the male. 



This insect varies considerably in colour, but is easily recog- 

 nisable, and the various named varieties hardly require detailed 

 notice.
