In the selection of the Uwang and Salagubang, the author mentions that Uwang is known in English as the Rhinoceros Beetle. The two species known as the Uwang and Salagubang have sharp claws which can be painful when they attach to someone.
They are also very firm that it would be difficult to get them off easily when they cling to a person. The writer, however, mentions that the sharp caws hurt when they glue to a person.
