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.
American Grannom
A case-building caddisfly whose larvae attach their cases to rocks in fast current and filter-feed. Cases are chimney-shaped and built from silk and plant fragments.
Did You Know?
Larvae can switch between filter-feeding and scraping algae depending on current speed.
