Neon Cuckoo Bee
Thyreus nitidulus

Exoskeletal Armor
To survive the wrath of a returning host bee, the Neon Cuckoo has a notoriously thick cuticle. Its body is a tank, designed to withstand stings and bites during nest invasions.
Structural Blue "Glow"
The brilliant blue spots are not caused by pigment. Instead, they are created by plumose hairs (setae) that have a "glowing" microscopic structure. This structure reflects light at a specific wavelength, creating a neon sapphire effect.
Chemical Stealth
Research suggests they may use chemical camouflage. By mimicking the scent of the host nest, they can avoid detection by the host's sensitive antennae once they are inside the dark tunnels.
