Eco-biology of the blue pansy butterfly, Junonia Orithya L. (Lepidoptera: Rhopalocera: Nymphalidae) from the east coast of Southern India


Author(s): Matala Bhupathi Rayalu and Pappu Kirankumar

Abstract: This study presents the first description of the life history of the Blue pansy butterfly Junonia orithya L., focusing on larval performance, specifically food consumption and utilization, and the duration of its life cycle on its host plant Evolvulus alsinoides (L.) L. The research was conducted in 2023 in Visakhapatnam, South India (17° 42' N and 82° 18' E). The complete life cycle of Junonia orithya spans 25 to 32 days (mean 27.40±2.89 days), with the following stages: Egg: 3 days; Larva: 16 to 22 days; Pupa: 6 to 7 days. Nutritional indices were measured across various instars under laboratory conditions, with a temperature of 28±2 °C and a relative humidity of 80±10%. The Approximate Digestibility (AD) ranged from 44.13% to 92.39%, Efficiency of Conversion of Digested food (ECD) from 1.92% to 25.56%, and Efficiency of Conversion of Ingested food (ECI) from 1.77% to 11.28%. These high ECD and ECI values likely contribute to the ecological success of J. orithya in the studied environment.
