About Diaphanes meghalayanus and Diaphanes mawlynnong
- The naming of Diaphanes meghalayanus reflects its wider presence across Meghalaya, while Diaphanes mawlynnong is named after Mawlynnong village in recognition of the local Khasi community.
- These species are adapted to cool and humid conditions, thriving in temperatures around 18–20°C with high moisture levels in the air.
- Unlike its counterpart, Diaphanes mawlynnong is more habitat-specific and is typically found in dense forests with thick bamboo clusters and rocky streams.
- meghalayanus has been observed in a variety of habitats, including semi-evergreen forests and betel nut plantations interspersed with bamboo.
- Both species prefer dark, undisturbed environments with minimal human interference.
- The male D. mawlynnong flies at considerable heights, whereas its wingless female remains concealed under rocks, offering rare insights into its behaviour.
- Their bioluminescent patterns differ, with females producing slower, longer glows compared to the quicker flashes seen in males, while D. meghalayanus can be spotted glowing softly as it flies above the ground at night.
