642 AN INTRODUCTION TO ENTOMOLOGY 



Family TORTRICID^ 



The Typical Tortricids 



The tortricidaj differ, as a rule, 

 from the preceding family in lacking 

 a fringe of long 

 hairs on the basal 

 part of the cubitus 

 of the hind wings. 

 In the fore wings 

 the distal part of pjg, -j^e.—Arch- 

 the first anal vein ips rosana. 

 is preserved, and 



vein Cu2 arises from a point before the outer fourth of the discal cell. 

 In a recent list 165 North American species 



are enumerated; these represent 15 genera. 

 Several of our better-known members of 



this family belong to the genus Archips. This 



is the genus Cacoecia of those writers who do 



not recognize the names proposed by Hiibner 



in his "Tentamen." These insects have been 



named the ugly-nest tortricids; ugly dwelling 



being the meaning of Caccecia, and also descrip- 

 tive of the nests of the larvae of these insects. 



The four following species are common. 



The rose ugly-nest tortricid, Archips rosana. 



— The larva of this species feeds within the 



webbed-together leaves of rose and a number 



of other plants. Figure 785 represents the nest 



of a larva in a currant leaf; and Figure 786 the 



adult of this species. This moth expands about 



20 mm. The fore wings are olive-brown, 



crossed by bands of darker color; the hind 



wings are dusky. This species differs from the 



two following in that each larva makes a nest for 



itself. 



The cherry-tree ugly-nest tortricid, Archips 



cerasivordna. — This species lives upon the 



choke-cherry and sometimes upon the culti- 

 vated cherry. The larv«, which are 3^ellow, 



active creatures, fasten together all the leaves 



and twigs of a branch and feed upon them 



(Fig. 787), an entire brood occupying a single 



nest. The larvse change to pupee within the 



nest; and the pupae, when about to transform, Pig.' 787. — Nest of 



work their way out and hang suspended from Archips cerasivor- 



the outer portion of the nest, clinging to it 



only by hooks at the tail end of the body. 



Here they transform.
