Cuc Phuong Butterflies
The lowest area of Cuc Phuong National Park and wettest layer of the forest is the litter layer. This floor receives almost no sunlight. The litter layer concentrates decomposing organic matter, forming a thick layer of humus that is a rich source of nutrients for lower plants such as moss and ferns.
This humid environment is also ideal for the growth of fungi and lichens.

Amidst the rotting corpses of plants and the green leaves rising from them, people can deeply feel a philosophy of nature: “Death is the beginning of life”.
Some kind of butterfly in Cuc Phuong National Park:

The aim of this article is to show the diversity of butterflies in Cuc Phuong, how this reflects the biogeographical changes in the region over the past 50-100 million years, behaviour patterns such as mimicry, camouflage, massing, host-plant relationships and the importance of the Cuc Phuong butterflies as environmental indicators.
