Abstract. — Fifty lepidopteran taxa were collected in association with greenleaf manzanita. Of these, 3 1 were collected from manzanita foliage as larvae and 29 were reared to adult-hood. A listing of taxa is presented including method of collection, life stage(s) encountered in the field, collecting locations, and parasitoids reared from collected specimens. Key Words: Lepidoptera, Arctostaphylos patula, greenleaf manzanita, parasitoids Greenleaf manzanita, Arctostaphylos pa-tula E. Greene (Ericaceae), is a broadleaf evergreen shrub that commonly occurs in the Sierra Nevada mountain range of the western United States (Hickman 1993). This particular manzanita species grows in mesic habitats associated with montane for-est zones generally above 303 m (1000 ft) in elevation (Ball et al. 1983). In general, information concerning insects and brush-field ecosystems (e.g. montane chaparral communities) is currently lacking in the lit-erature (Force 1990); this is certainly the case concerning herbivorous insects asso-ciated with greenleaf manzanita (e.g. Haws et al. 1988). In response to the growing concern over a limited number of control options for greenleaf manzanita shrubs which compete with more economically im-portant timber species, a study was con-ducted from 1989 to 1994 to evaluate the potential of using native insects to alter vegetative composition (Valenti 1994). More than 500 insect species were identi-fied in association with greenleaf manzani-' Present address: Delaware Department of Agricul-ture, 2320 S. Dupont Hgwy., Dover, DE 19901-5515.

In ad-dition, records of parasitoids and other nat-ural enemies, when available, are presented for a number of species. Materials and Methods Site descriptions. — Bear Wallow. This 20+ ha, old-growth greenleaf manzanita brushfield (elevation 1524 m [5000 ft]) is located 3 km (by dirt road) from CA Route 89 in Old Station (approximately 6.6 km south southwest of the Logan Lake site) (T32N R4E SIO). Greenleaf manzanita, which averaged 1.5-2.0 m in height, ac-counted for approximately 85% of the total vegetation. Hat Creek. Located adjacent to the USDA Forest Service Work Center, Hat Creek, CA (T34N R4E SI 6) (elevation 1018 m [3340 ftj), this site consists of a variety of woody plant species. Greenleaf manzanita is fairly common but accounted for less than 30% of the total vegetation. Other plant species present at this site in-cluded: sagebrush (Artemesia tridentata
