Abstract

Morphological characterization of two species of snout moths, Elophila difflualis (Snellen, 1880) (Crambidae) and Ephestiopsis vishnu Roesler and Kuppers, 1981 (Pyralidae) is presented. Differential shading of Azolla at 35, 50 and 70% significantly influenced the numerical abundance of these moths with mean larval numbers of both the species being the maximum under 35% shade. Further, E. difflualis (13.11) outnumbered E. vishnu (7.22) and the larvae of E. difflualis seemed to be temporarily displaced in the presence of E. vishnu.
