CATOCALA: UNDER=WINQS. 



I have told, in this little book, something about all the 

 sorts of insects' eggs which have excited the curiosity of 

 my uri specialized visitors and correspondents. Of course, 

 my experience is limited; tomorrow, some one, not a 

 specialist nor an advanced amateur, may ask a question 

 which I have not been asked before and very possibly 

 I will be unable to answer it. 



Catocala ultronia (Plate LIII) is a variable species, 

 several forms having been given distinctive names. The 

 larvae feed on plum, apple, and wild cherry leaves. The 

 pupae in their cocoons, which are formed in July under 

 chips or dead leaves, are covered with a bluish, easily 

 rubbed bloorn. Adults fly from late July to October. 

 Eggs are well hidden in crevices of the bark of their food- 

 trees. 



Catocala cara (Plate LIII) larvae, on willow and poplar, 

 have a purplish head streaked and spotted with pale tes- 

 taceous ; their bodies are light to dark clay or wood brown ; 

 on each side of the back is a smoky, longitudinal band and 

 a wavy, broken one on each side along the spiracles; 

 the dorsal warts are dull carmine or yellowish-brown ; the 

 underside is reddish, with a large black patch between 

 each of the first three pairs of abdominal legs. Adults 

 are to be found from July to September. 



Catocala relic ta (Plate LIII) larvae feed on poplar and 

 also, probably, willow and white birch; they are greenish- 

 white, thickly spotted with yellowish-brown, the ninth 

 and twelfth segments and the head being marked with 

 black. The cocoon is rather thick and is usually made in 

 fallen leaves, drawn together by the larva. Adults, of 

 which there are several named forms, appear from July 

 to September. 



Catocala vidua (Plate LIII) larvae eat walnut, butternut, 

 hickory, and oak; they are pale lilac with stripes composed 

 of black dots, giving a gray appearance; their heads are 

 striped with dull lilac and white and have orange spots, 

 above, with a black hair in the center of each. Pupation 

 is said to occur in June; most of our adult specimens were 

 caught in August and September. 



Plate LI V shows Catocala concumbens, larva on willow and 

 poplar; C. grynea, larva on apple and plum; and C. arnica.
