AUTECOLOGY OF THE COMMON CROW BUTTERFLY

S.P. Venkata Ramana, J.B. Atluri and C. Subba Reddi

Abstract

The common crow butterfly Euploeo core is multivoltine, and breeds almost throughout the year with higher frequency during the period from November through January (winter season). The development from egg to adult required 28- 30 days. The larve passed through five instars at the laboratory temperature of 28°C. The growth of larvae was directly correlated with the quantity of food consumed. Food utilisation efficiencies across the instras indicated that ECD and ECI are inversely related. The AD values (98.0 to 82.8%) decreased from first through subsequent instras whereas the ECD (10.9 to 41.30) and ECI (10.00-34.20) values increased. The adults foraged on nearly 25 floral species with sucrose dominant nectars.
