A gigantic moth that is almost never seen by humans was recently found on a building site at a school in Australia. The colossal insect is so heavy that it can’t fly, and reaches its full size just a few days before mating. And then it dies.
Giant wood moths (Endoxyla cinereus) are the largest species of moth in the world. When fully grown, the females, which are around twice the size of the males, can weigh up to 1 ounce (30 grams) and reach a wingspan of 10 inches (25 centimeters).
