As of Jun 19, 2026, 8:54 PM, out of season, returns ~November. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Nighttime boat tours on the Loboc and Abatan rivers reveal dense congregations of mangrove fireflies (Pteroptyx spp.) that flash from mangrove trees along the river edge.
The displays are strongest on dark, calm nights and are presented via local guided boat operators who navigate quiet waterways to view the glowing trees.
