What to know about Amber fossil reveals firefly relative with unprecedented antennae

Researchers have discovered a 100-million-year-old fossil of a lampyroid beetle, named Icaroramus perisi, in Kachin amber from Myanmar. The specimen is notable for its unique 'quadriheteroramose' antennal architecture, which suggests complex sensory capabilities in extinct firefly relatives.

What happened

August 17, 2026 feature Amber fossil reveals firefly relative with unprecedented antennae Ingrid Fadelli Author Lisa Lock Scientific Editor Robert Egan Senior Editor Insects rely on a wide range of strategies to sense their surroundings and communicate with…

Why it matters

Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical reactions that take place in specialized light-producing organs.

Common ground

Many firefly species use these bioluminescent signals to communicate with potential mates, while some also use them to defend themselves from predators.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
