within the vicinity of the Seneca II-W area, however, the peregrine may travel through • the area when migrating. Reptiles and Amphibians. The amphibian and reptile species which have been observed on the Seneca II-W study area are included in Ta 61e 11-13 along with a list of those species which could occur on the study area according to preferred habitat and species d~i stribution. Several large prairie rattlesnakes (C rotalus vi ri dis) have been road killed on County Road 53 along Dry Creek throughout the 1979 summer field period. A small r~ittlesnake was observed on a sagebrush covered knoll near big game pellet group transect Pf,-1 during the August 1979 pellet group plot inspection. A northern sagebrush lizard (:iceloporus graciosus) was observed in sagebrush habitat. Other reptiles and amphibians sighted on the study area were observed near streams or gully bottoms. Invertebrates. Results of the insect sweep sampling are given in Tables 11-14 through 11 -18. Relative diversity of the invertebrate population and total numbers captured at each sampling site are presented within these tables. Diversity of insect groups was the h ~ighest at site 1 (forb vegetation) with total numbers being relatively high also. Abundant families at this site included Curculionide (snout beetles) of the order • Coleoptera (45 percent of the total numbers). The sedge meadow (site 2) sample contained Cercopidae (frog hoppers) of the order Homoptera, comprising 22 percent of the total numbers, with Miri doe (plant bugs) and Lygari doe (seed bugs) of the order Himpitera making ul~ 20 and 42 percent of the total numbers, respectively. Curculioni doe was the most alwndant family in the sagebrush type at site 3 with 48 percent of the total numbers. Fo rmicidae (ants) of the order Hymenoptera comprised an additional 20 percent of the insect population. Site 4 (forb vegetation) had Tephritidae as the most abundant family with 53 percent of the total numbers. All site locations are depicted on Exhibit 11-3. D.jta from the May 1974 samples are indicative of insect populations on grazed rangeland. Tlie following discussion is a short description of the major insect families occurring on the study are a.Curculionidae are almost exclusively phytopha you s. The larvae attack all plant parts and usually live within the plant tissue. Adults feed on plant tissue, pollen, flower tissue, developing fruit, and occasionally on fungi. Adults do not necessarily feed on those plants preferred by the larvae. Host specificity is high in this group with most beetle species restricted to certain plant species. • the larvae of Tephritidae are mainly phytophagous; a few species are capable of forming 24
