The Diversity of Grasshoppers in Liwa Botanical Garden Based on Time Capture

Grasshopper is one of the diurnal cosmopolitan insect, the existence of grasshoppers is very influential for some other animal populations such as birds. It is still lack of information of diversity, distribution, population, and other basic biological aspects of grasshoppers at Kebun Raya Liwa (KRL). To monitor biodiversity, it is necessary to provide informations about  the number of individuals, their functions, and roles in the habitat and ecosystem. Therefore it is necessary to conduct  the research of  these topics. This research was carried out during  November to December 2019, at the Taman Hias Kebun Raya Liwa. Grasshoppers were cached in the morning from 06.00 AM to 09.00 AM, day from 10.00 AM to 02.00 PM, and afternoon   from 03.00 PM  to 06.00 PM . The grasshoppers was cached using a sweeping net by exploring the Taman Hias Kebun Raya Liwa. The caught grasshopper was identified at the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences, Universitas Lampung. The result show that  ten species of grasshopper were found at the Taman Hias Kebun Raya Liwa, i.e. Phaleoba antennata, Phaleoba fumosa, Phaleoba rustica, Atractomorpha crenulata, Atractomorpha sp. , Phillium crurifolium, Phillium sp, Trilophidia annulata, Oxya chienensis, and Melanoplus differentialentialis . The index  diversity of grasshopper at the Taman Hias Kebun Raya Liwa is categorized to moderate  with H' = 2.223. The best time to catch grasshoppers is in the morning from 06.00 AM-09.00 AM and afternoon from 03:00 PM – 05:00 PM .
