A menacingly large insect was caught on camera crawling up the walls of a building in Brazil. <br /><br />The winged critter with large mandibles is a Dobsonfly, an aquatic insect that are found around Asia, the Americas and southern Africa. <br /><br />The filmer explained: "The one in the video is a female of the species Corydalus batesii. Although it has terrifying jaws, the males have much longer ones. <br /><br />"Between two and three thousand eggs are laid on leaves, rocks, or any other materials in contact with unpolluted water. The larvae are aquatic, and are between 5 and 7 cm long. <br /><br />"They can live like that for five years, preying on smaller aquatic organisms, and taking shelter in submerged tree hollows. <br /><br />"When they finally leave the water, they dig a hole in the ground, sometimes under a rock or a tree, where they undergo they pupate for about a month, when they emerge as the winged insect seen in the video. <br /><br />"They can go through 12 stages of development in total, and the adult form only lives between 8 and 24 days."
