This type of grasshopper is a leaf-eating insect. Because it often damages coconut plants, it has recently become a pest that often harms coconut farmers. Several years ago, around the 1980s, this insect attacked thousands of coconut trees belonging to farmers in Siau.  This condition causes farmers to experience losses because crop yields decrease significantly. This condition forced the local government at that time, through schools, to order students to look for breeding places for these insects. to collect and eradicate these insect eggs   This is intended to stop the reproduction of these insects. and it worked.

 This type of fern leaf is known on the island of Siau as Potoraha. For the people of Siau, the leaves of this plant are no longer foreign, because they are easy to find in the village. There is one interesting thing about this plant. According to the natural knowledge of the local community, this plant can be used to stop bleeding in freshly scratched wounds. Therefore, the Siau people from Saman previously gave this plant the name Potoraha, because it comes from two Siau language syllables, namely: Poto and Raha. POTO which means cut or break or stop. And RAHA which means Blood.  which can be interpreted as stopping the blood. The part used to stop the blood is a brown powder or known as the spores attached to the stem.
