Research conducted by Flora Fauna Nusantara in 2022 at the Bandealit Resort area of Meru Betiri National Park documented a variety of dragonfly species (Odonata) inhabiting the region. Through observations carried out across several habitat types, the research team successfully recorded 12 dragonfly species, including several species known to be endemic to Java.
The recorded species included:
- Copera marginipes
- Euphaea variegata
- Vestalis luctuosa
- Nososticta insignis
- Ischnura senegalensis
- Heliocypha fenestrata
- Crocothemis servilia
- Orthetrum sabina
- Pantala flavescens
- Neurothemis ramburii
- Diplacodes trivialis
- Trithemis festiva.
The presence of dragonflies within the Bandealit ecosystem highlights the importance of the area in supporting freshwater-dependent insects that are highly sensitive to environmental changes. Dragonflies are widely recognized as natural bioindicators because their life cycle depends on both aquatic and terrestrial habitats. Their occurrence suggests that the environmental conditions, particularly water quality, remain suitable for sustaining their development from aquatic larvae to adult stages.
The study also revealed differences in habitat preferences among species. Some dragonflies were commonly observed in shaded and humid environments, while others were more frequently encountered in open areas with higher sunlight exposure. This variation reflects the habitat heterogeneity of the Bandealit area, which supports diverse ecological niches for different species.
In addition, the findings emphasize the ecological significance of maintaining healthy freshwater ecosystems and surrounding habitats. Environmental disturbances and habitat degradation may directly affect sensitive insect groups such as dragonflies, making conservation efforts essential for preserving biodiversity and ecosystem stability in the region
