Butterflies and locality predict the occurrence of larger day-flying moths in Dehing Patkai landscape, Assam

Author(s): Subhasish Arandhara
Abstract: This paper deals with a survey of day-flying moths from Dehing Patkai landscape, Assam covering a period from 2014 to 2017. 10 species belonging to 10 genera from 6 families were encountered in the study. The moths were sighted more in the morning hours, in the month of October, in the forested land and roadsides. Multiple logistic regression analysis revealed that presence of day-flying moths were positively related to the abundance of butterflies, for 5 out of 7 moth species analysed. Test for moth abundance showed significant difference between the categories of locality (X2, p=78.034, 0.000); sighting hour (X2, p=8.67, 0.03); distance to forest (U, p= 844.5, 0.00); distance to industries (U, p= 1249, 0.007) and distance to human settlements (U, p=1031.5, 0.02). Day-flying moths and butterflies overlap in time, locality, resource requirements and susceptible to similar threats. Both the groups may play surrogate role in conservation alternately for each other.
