Trictenotoma childreni, the log-boring beetle or brown steampunk beetle, is a species of beetle in the Trictenotomidae family. It can reach a body length of about 55-65 mm. Basic color of these large beetles is black, the body is slightly flattened, and it is covered with thick grayish-yellow hair. It has large eyes, long antennae and legs, and powerful mandibles. This species can be found in Malaysia, Myanmar, Borneo, Thailand, Indonesia, Vietnam, China, and India in damp and seasonal forests.
The wings of Trictenotoma childreni are known to fluoresce under illumination by ultraviolet light. Their fluorescence properties are however, not comprehensively documented. The optical properties of the Trictenotoma childreni yellow longhorn beetle, were investigated using both linear and nonlinear optical methods, including one and two photon fluorescence and second harmonic generation. These three distinct optical signals discovered in this beetle are attributed to the presence of fluorophores embedded within the scales covering their elytra. Experimental evidence collected indicates that the fluorophores are non centrosymmetric.
