![]() ![]() This research was published 11 March, in the New Journal of Physics. Fully grown grubs of the Hercules beetle are prime tucker for bears, raccoons, and other wildlife. Rhinoceros beetles like this male Hercules beetle use their impressive horns to battle each other for access to mates. This could be useful for example in food processing plants to monitor the moisture level." A giant among beetles: Hercules beetle, Dynastes tityus. Such materials could be put to work as humidity sensors. Marie Rassart, who did the research at the University of Namur, said, "The sort of structural behaviour displayed by the Hercules Beetle could be an important property for 'intelligent' materials'. The techniques used to study the beetle's morphology included new scanning techniques for electron images which over recent years have been refined to yield great depth and therefore help to create three-dimensional images of miniscule structures. Others have suggested that it is to do with warmth absorption at night. You must be right because the picture of the WESTERN HERCULES BEETLE looks exactly like the one I found on my bathroom floor. Some have suggested that it is to do with protection - it becomes more humid at night and is therefore good for cover to turn black. We found at least 10 adult Hercules beetles, both male and female on a tree Ina preschool playground in central Maryland last late June. As although dry specimen of the shell could be relied on to change when humid conditions were introduced, the living specie that researchers also had in the lab were not as consistent.Īs to why the beetle changes colour, question marks also remain. The beetle, usually found in the rainforests of Columbia, Venezuela, Peru, Ecuador, Bolivia, and Brazil, is still rather mysterious though. The researchers used dry specimen of the beetle's shell to test in laboratory conditions. When water penetrates through the widely-open porous layers, it destroys the interferences phenomenon leading to a black colouration. The light interferes with the structure to produce the green colour of the shell. Researchers from the University of Namur in Belgium have used the latest imaging techniques to study the shell of the beetle - a scanning electronic microscope to determine the structure responsible for the colour and a spectrophotometer to analyze how the light interacts with this structure. Insects flat linear long shadow icons set. ![]() ![]() The Hercules Beetle is remarkable, not only for its strength, able to carry up to 850 times its own weight, the protective outgrowth of the insects' exoskeleton, aka its shell, also changes from green to black as its surrounding atmosphere gets more humid.
