Ben Tre Fireflies Keeps the Unknowns in the Field Notes
An evidence-led field journal documenting fireflies, river habitat, bần trees and responsible viewing in Ben Tre, Vietnam.
Field notes
The project uses an explicit evidence policy: local observations are kept distinct from scientific findings from other regions, and the monitored population remains unidentified. Its archive includes a Vietnamese field note with an English translation, a photograph credited to Thuần, and a short riverbank video whose lights are not exposure-enhanced. The site also records an observation from 28 Aug 2026 while cautioning that a single exceptional night cannot establish a season or explain variation.
