Borneo Firefly

A synchronous firefly endemic to Borneo that creates dramatic light displays in riverside trees. It congregates in specific display trees night after night.

💡

Did You Know?

Individual display trees can host the same colony for decades, and the loss of a single tree can displace thousands of fireflies.

Map Butterfly

A small butterfly that produces two dramatically different seasonal forms within the same year. Spring adults are orange with black spots; summer adults are black with white bands.

💡

Did You Know?

The seasonal colour change is triggered by day length during the larval stage, not temperature.
