THE SEASONAL VARIATIONS OF BUTTERFLIES AT SATHCHARI NATIONAL PARK, HABIGANJ, BANGLADESH

The tropical semi-deciduous Satchari National Park lies in northeast Bangladesh. Elevational gradients and the local microclimate make Bangladesh's northeast butterfly habitat more diverse and abundant. The tropical rainforests of
Bangladesh were teeming with wildlife. Nature conservation focuses on
maximizing plant, animal, and plant-animal connection diversity on a global
scale. It was essential to the natural populations of plants and animals.
Identifying and evaluating the floral and faunal diversity of an ecosystem helps
protect forests. Insects play a crucial role in the evaluation of forests for biological
resource conservation (Kim, 1993; Samways, 1994), and butterfly diversity and
their characteristic links to environmental variables such as plant diversity, floral
wildness, habitat maintenance and complexity, landscape and forest structure,
topography and moisture gradient, climate, and others are good subjects for the
ecological study of forests (Molina & Palma, 1996; Spitzer et al., 1997). Elevational gradients and microclimates contribute to the
richness and diversity of the butterfly fauna in northeastern Bangladesh. Satchari National
Park contains 195 species of butterflies from 6 families(Hasan, 2018). As before, (Hasan,
2018) conducted a study from 2015–2017 on butterfly species and seasonal change. In
this study, we demonstrated the current seasonal variation of butterfly species and the
relationship with Hasan (Hasan, 2018).
