Wasps are building fluorescent nests

Wasps are building fluorescent nests A team of scientists say they have come across the first known case of animals building fluorescent houses. In a new study, they detail the finding of nests built by certain species of wasps that glow green under exposure to ultraviolet light. What's more, wasps of the same family in other parts of the world also appear capable of creating similarly creepy structures. The discovery occurred during an expedition to northern Vietnam, but not intentionally, according to the scientists. Study author Bernd Schöllhorn, a professor of chemistry at the University of Paris, told Live Science that they traveled with ultraviolet lights in the hope of stumbling upon any fluorescent bugs after dark. Instead, they found wasp nests with cocoons (woven silk structures that cover the nest and keep the larvae safe) that emitted a bright mucus-green glow when exposed to ultraviolet light between 360 and 400 nanometers wavelength at night.
