arising from dark tubercles. Crotchets of prolegs biordinal, those of 

 anal prolegs in two groups. Head dark reddish brown. Antennae yel- 

 lowish brown. Thoracic shield broad, a variable brown ; body light 

 brown, longitudinally marked as follows : median stripe reddish brown, 

 submedian stripes whitish, sublateral dark brown, lateral ones light red- 

 dish brown, all somewhat interrupted ; thoracic legs dark brown, prolegs 

 yellowish white, apically light brown ; anal plate reddish brown, pos- 

 terior margin dark. 



Pupa. Length about 5.5 mm. Slender, reddish brown ; wing cases ex- 

 tending to fourth abdominal segment ; terminal segment subacute, nar- 

 rowly rounded with a cluster of 5 or 6 irregular, long, slender, hooked 

 spines. 



Adult. This was described by Fabricius in 1781 (Spec. Insect. 2:307) 

 as Alucita ttwrfjhiclla, the original description being as follows: "alls 

 fusco nitidis, marginibus niueis. Habitat in Juniperetis Angliae. Mus. 

 Dom. Yeats. Media. Palpi carassi, bifidi, interne niuei, externe fuscae. 

 Caput niueum, antennis fuscis. Alae anticae fuscae, nitidae margine in- 

 teriore et exteriore late niueo. Posticae exalbidae immaculatae." 



The adult is rather attractive. The forewings are brown 

 with white front and rear margins, the white disappearing 

 before reaching the apex of the wing. The hind wings are 

 uniformly pearl gray above and below, shining and heavily 

 fringed. The thorax and abdomen above and below are light 

 brown with a tuft of creamy white hairs on the head and 

 prothorax. The wing spread is about 15 mm., and length about 

 7 mm. 



According to Rebel 4 this species occurs in Europe except the 

 polar regions and Siberia. Meyrick 5 mentions several English 

 localities. Central Europe and Northern Asia. He also lists 

 another species, YpsolopJuts junipcrellus, as occurring in a web 

 on juniper. 



For the control of this species, it is recommended that in- 

 fested plants be sprayed or dusted with arsenate of lead during 

 the last of June or first part of July when the webs are small, 

 weak and easily penetrated. Later a dust could not be used 

 and a spray would be necessary to penetrate the more closely 

 webbed foliage. On some varieties of juniper, the dried nests 

 containing caterpillars could be cut and burned early in the 

 spring.
