A list of otter <br /> reptiles cu'1C1 an„�.:,lblan species tllctt niLLght occur iI^n 'habitats or. or rnf % t Ie <br /> study area are provided in Table 1 . <br /> Sweep-net samples were collected in grassland pasture and upland sage- <br /> brush vegetation on the study area and at a revegetation plot at the Seneca <br /> II mine during June, 1979 to dete_nrLine abundance of flying insect groups <br /> and to ascertain if densities of any groups nay pose a potential problem <br /> to revegetation success. The results of this survey are presented in <br /> Table 5 . The grassland pasture type contained t;ie highest nu-rber of <br /> insects an-enable to collection by the sweep-net met:od (17.2 insects/m2} <br /> followed by the revegetation site (2.5 insects/m2) and the upland sage- <br /> brush type (1.9 insects/m2) . Also, samples from grassland pasture contained <br /> the highest diversity of insects with 19 groups represented. Plant bugs <br /> (Family Miridae) dominated samples fron-n 'JZis type, accounting <br /> for over 88% of all insects collected. Seed bugs (Family Lyc-.Fe.idae) was <br /> the only other group frequently encountered in grassland pasture and <br /> accounted for 7.4€ of the total density. Plant bugs are considered a <br /> serious pest of cultivated plants wrv_le seed bugs, so called Decau,e they , <br /> feed A-Tnstly on seeds, are often coaLti n on vegetation (Borrow and tnhite <br /> 1970) . <br /> Plant bugs and seed bugs were also the n-;nst co„=�iC_'ir. species fog rd on the <br /> revegetation site but were far less ca—on than on grassland pasture W1t^1 <br /> only 1.5 and 0.4 insects/m2 respectively, as compared to 15.1 and 1.3 <br /> insects/m2, respectively, for grassland rastdre. Fewer groups (12) were <br /> also recorded in the revegetation area. Stink bugs (F anily Pentatorlidae) <br /> were also fairly common on the revegetation site accounting for alrnost <br /> 13% of the total insects collected. Nbst of the niambers of this group of <br /> bugs are plant feeders, although sorre are predaceous. A mew of the plant <br /> feeders occasionally damage cultivated plants, especially fruits. <br /> Tho s, '�-iinigh type containec! tiie fewest nitmi)or n; inso7—r- (I .n <br /> insects/m2) an(i the nim-)er of ins.--r r,rnt;ps (i i Tpaf, :tiN-1 7 e� <br /> -45- <br /> J U N 1 1 1980 <br />
