Indonesia is one of the countries in the world that has a very high biodiversity, both flora and fauna, this is because Indonesia's topography is composed of islands and each island has its own characteristic ecosystem. Ecosystem is influenced by several things, one of which is the height of an area. This research was conducted in 3 sub-districts in Malang Regency, namely Poncokusumo District which has a height ranging from (729-2365 masl), Lawang District has an altitude (454-603 masl), and Bantur District has an altitude (303-357 masl). The results of research on spiders based on differences in height in Malang Regency: Location of Poncokusumo (1482m above sea level) at the location of the ecosystem where the highest IVI of spiders is shaded is the genus Leucauge, namely 1.54, while in open ecosystems the highest IVI value is obtained by genus Tetragnatha 1.60 and index The highest diversity was obtained by the genus Leucauge 0.5, Location Lawang (446m asl) at the location of the ecosystem that was shaded by IVI of spiders, the highest was genus Laucauge, namely 0.61, while the highest diversity index was obtained by genus Argiope 0.5 Whereas in the open ecosystem the highest IVI value was obtained by the genus Leucauge, namely 2.08 and also had the largest diversity index, which was 0.33, Bantur location (321mdpl) in the location of the highest IVI spider ecosystem was Leucauge genus, namely 1.54 and index The highest diversity was obtained by the genus Tetragnatha and Laucauge which was 0.5. Whereas in open ecosystems the highest IVI value was obtained by genus Tetragnatha 1.60 and the highest Diversity Index was obtained by genus Leucauge 0.53.
