Yellow Sally
A bright yellow stonefly common in European upland streams. Nymphs are omnivorous, feeding on both algae and small invertebrates.
Did You Know?
The vivid yellow color serves no known warning function and fades quickly in preserved specimens.
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.
