Ignelater luminosus, also known as the cucubano, is a special type of click beetle. You can find this amazing insect only on the island of Puerto Rico. Cucubanos are famous for their ability to glow in the dark! They are sometimes confused with fireflies, but they are actually different kinds of insects.

What Makes a Cucubano Special?
Cucubanos are unique because they can make their own light. This is called bioluminescence. They have special light organs on their body.
How Cucubanos Glow
A cucubano has two light organs on its chest area, which is called the prothorax. These look like two bright "headlights." It also has one light organ on the front part of its abdomen, which acts like a "backlight." The cucubano can turn these lights on and off whenever it wants! This makes them look like tiny glowing cars flying through the night.
Where Cucubanos Live
Cucubanos love quiet, natural places. They prefer rural areas where there aren't many buildings or bright city lights. This is because too much light from cities, called light pollution, can make it hard for them to find partners and reproduce. One place where many cucubanos live is in the mountains around the town of Adjuntas in Puerto Rico.
Size of a Cucubano
These glowing beetles are about 1 in (25 mm) (2.5 centimeters) long. That's about the length of your thumb!
Cucubanos vs. Fireflies
Even though cucubanos glow, they are not true fireflies. True fireflies belong to a different insect family called Lampyridae. In Puerto Rico, there's a true firefly called a cucullo.
Cucullo: Puerto Rico's True Firefly
The cucullo is also native to Puerto Rico and can glow. However, cucullos are smaller than cucubanos, usually only about half an inch (1.25 centimeters) long. Both cucubanos and cucullos produce a bright green light.
Cucubano Science
Scientists are very interested in the cucubano's ability to glow. In 2018, scientists studied the Ignelater luminosus very closely. They mapped out its entire genome. A genome is like a complete instruction book for how an organism is built and how it works. Studying the cucubano's genome helps us understand more about how it makes light and how it lives.
