Selorejo Waterfall is a natural tourism area that is quite far from downtown Ponorogo and directly adjacent to the Gunung Sigogor Nature Reserve. Hence, this area has the potential as a natural habitat for dragonfly and damselfly. The presence of dragonfly and damselfly species is determined by the type of habitat, canopy conditions, vegetation diversity, and the microclimate that exists in a location. This study aimed to determine the diversity of dragonfly and damselfly and to determine the community structure of dragonflies in Selorejo Waterfall. The sampling method was Visual Day Flying. The results of research conducted in two streams showed that there were 12 species from 6 families with a total of 230 individuals. The value of species diversity at this location is H '= 2.05. In the community structure at the Selorejo Waterfall dragonfly, there are differences in the number of species and individuals in the two streams in Selorejo Waterfall Area. The large stream, eight species from four families, 151 individuals in total. Meanwhile, in small stream, there were nine species from six families, 79 individuals in total. The differences in the number of species and individual dragonflies in the two streams at Selorejo Waterfall can be used to describe the diversity and structure of the Odonata community in the area.

The rice field area of ​​Warugunung Village is an agricultural area with a pond. In rice fields there are various kinds of insects and ponds which are aquatic habitat types with great potential as natural habitats for dragonflies (Odonata). Dragonflies are flying insects that have an important role in the ecosystem, namely maintaining the balance of the food chain by being a predator for insect pests. This study aims to inventory and determine the composition of dragonflies found in the rice fields of Warugunung Village, Surabaya. The research method used is the VES (Visual Ecounter Survey) method and belt transects, as well as data analysis using the Shannon-Wienner (H') species diversity index formula. The results obtained were 17 species from 3 families with a total of 139 individuals. The results of the diversity index analysis show that the lowest diversity index is found at the Vegetation Pond observation location with a value of H'= 2.41 and the lowest diversity index is at the rice field observation location with a value of H'= 1.27.

Mount Sigogor Nature Reserve area is a mountainous tropical rain forest, administratively located in Pupus Village, Ngebel District, Ponorogo Regency, East Java, Indonesia. One of the main functions of this nature reserve is as a water catchment area for the villages around the nature reserve area. Water sources and flows within the Mount Sigogor Nature Reserve area have the potential as natural habitat for dragonflies. This study aims to determine the diversity and abundance of dragonflies (Odonata) in the Mount Sigogor Nature Reserve Area. The method of collecting dragonflies data used the Visual Day Flying method by recording the diversity of dragonflies species and counting the number of individuals from each observed dragonflies species. The data obtained were analyzed using the Relative abundance, Shannon-Wiener Heterogeneity Index and the frequency of Presence. The results of the research conducted showed that there were 14 species from 7 families with a total of 464 individuals. The Shannor-Wiener diversity index shows that the diversity value is H'= 1.81. Meanwhile, the presence frequency analysis showed that there were four species with a value of 100% which were classified as abundant Frequency of Presence, namely Euphaea variegata, Vestalis luctuosa, Rhinocypha anisoptera and Coeliccia membranipes.

The Sumur Penguripan Cultural Reserve is an area of clean water wells in which there are two types of ponds, namely Canopied and Non-Canopied, with unspoiled environmental conditions. So, this area has potential as a natural habitat for the dragonfly community. The community of dragonflies at a location can be an environmental indicator, especially in waters, and also be used as a biological control for the terrestrial environment. This study aimed to report differences in the dragonfly’s structure community from the two types of canopy in the pond area of the Sumur Panguripan Cultural Reserve. This study uses the Visual Encounter Survey (VES) method was modified using the Belt Transect method. The results of a study conducted in this location found that there were 20 species from 4 families, with 294 individuals. The value of species diversity of dragonflies at non-canopied locations is H’= 2.26, highest than the value of species diversity of dragonflies at locations with canopied that is H’= 1.87. At the canopied pond location, there were eight species with 48 individuals from 3 families. Meanwhile, at the Non-canopied pond location, there were 18 species with 246 individuals from 3 families.

Selorejo Waterfall is a natural tourist area that is directly adjacent to the Sigogor Mountain Nature Reserve and has a beautiful and natural environment. This makes the Selorejo Waterfall area has a good environment for the sustainability of various species of butterflies. This research aimed to find out the diversity and abundance of butterflies in the Selorejo Waterfall area. This research was conducted using the Visual Day Flaying method by following the trail in the Selorejo Waterfall area. This study found 26 species belongs 4 families with 109 individuals in total. The value of the species diversity index at the location of H'= 2.81 moderate category. The diversity of butterflies in the Selorejo Waterfall area was influenced by the availability of host plants and feed as well as abiotic factors.
