Studi Perilaku Berjemur Dalam Termoregulasi Pada Beberapa Kupu-Kupu Famili Nymphalidae
Basking behavior is an important process for butterflies to start their daily activities. Some factors might influence the posture and duration of basking are wing colours, wing span size, air temperature and light intensity. This study aims to analyze the posture and duration of basking behavior between Junonia atlites and Junonia hedonia, and Ypthima sp. and Mycalesis sp. The butterflies are followed and their basking activity is recorded for 120 seconds, followed by measurements of air temperature and light intensity. The frequency of basking postures exhibited and the average duration of basking were used for calculations using the t test. Furthermore the regression test was used to see the relationship between air temperature and duration of basking. The results showed that J. atlites and J. hedonia demonstrated the highest frequency of appressed or horizontal postures (94.44% and 63.33%) in the morning, conversely the frequency decreased at subsequent times. While Ypthima sp. and Mycalesis sp. displays closed postures with high frequency at all times. The results also revealed that neither body size nor wing color is not affected on the posture exhibited (P> 0.05). The duration of basking in the four species was found to be shorter when the air temperature increased, but there was no significant effect (P> 0.05). Also, the duration of basking is not affected by body size, or wing color (P> 0.05).
