The Frégate Island giant tenebrionid beetle (scientific name: Polposipus herculeanus) is a special type of beetle that cannot fly. It belongs to the darkling beetle family, known as Tenebrionidae. This amazing insect is only found on Frégate Island in the Seychelles, making it endemic to that one small island.
These beetles can grow to be about 20 to 30 millimeters long, which is roughly the size of your thumb. They have a hard, rounded body covered in small bumps called tubercles. It's hard to tell the difference between male and female beetles just by looking at them because they look very similar.

Where They Live and What They Do
The Frégate Island giant tenebrionid beetles spend most of their time living in trees. During the day, they hide under tree bark, in the bends of branches, or inside bushes to stay safe.
Nighttime Adventures
These beetles are mostly active at night. When the sun goes down, they come down from the trees to the forest floor. However, they don't travel very far from their hiding spots. This behavior helps them avoid animals that might want to eat them, like the Wright's Skink (a type of lizard) and the Seychelles magpie-robin (a bird).
Special Defenses
If a Frégate beetle feels like it's in danger, it has a cool way to protect itself! It can spray a special liquid from glands at the back of its body. This liquid has a musky smell and can even stain skin purple. It's a great way to tell predators to back off!
What They Eat
In places where they are cared for by people, like zoos, these beetles eat a variety of foods. They enjoy fruits, vegetables, tree bark, and even fungus. Sometimes, they've even been seen eating cat food!
Protecting the Frégate Beetle
The Frégate Island giant tenebrionid beetle is a vulnerable species, meaning it's at risk of disappearing forever. To help protect them, some of these beetles are kept in zoos and special conservation centers. The largest group of these beetles outside of their natural home is at London Zoo. These beetles are descendants of a few small groups that were brought from Frégate Island many years ago.
Scientists believe that these beetles might have lived on other islands in the Seychelles in the past. There's an idea that they could be moved to other islands to help them spread out and become less vulnerable. When cared for by humans, these beetles have been known to live for up to seven years, which is a long time for an insect!
