Abstract
This study presents the first detailed account
of the life history of the common sailer butterfly, Neptis hylas
(Linnaeus, 1758), focusing on larval performance in terms of food consumption,
utilization, and the duration of its life cycle on the host plant Triumfetta
pentandra A. Rich. Conducted in 2023 in Visakhapatnam (17° 42' N, 82° 18'
E), South India, the research found that the butterfly completes its life cycle
in 27 to 41 days, with an average of 34.00 ± 6.13 days. The stages of the life
cycle include the egg stage (4 days), larval stage (16-26 days), and pupal
stage (7-11 days). Nutritional indices measured across the instars included
Approximate Digestibility (AD) ranging from 49.56% to 97.71%, Efficiency of
Conversion of Digested food (ECD) ranging from 4.63% to 34.22%, and Efficiency
of Conversion of Ingested food (ECI) ranging from 4.52% to 16.89%. These
measurements were taken under controlled laboratory conditions at a temperature
of 28 ± 2°C and relative humidity (RH) of 80 ± 10%. The relatively high values
of ECD and ECI observed in this study partially explain the ecological success
of N. hylas in the given environment.
