Abstract-Variations in the patterns of asymmetry in coconut leaf beetle Brontispa longissima metasternum from ten (10) populations in Northern Mindanao, Philippines were evaluated using the landmark-based advanced geometric morphometrics Symmetry and Asymmetry in Geometric Data (SAGE) version 1.04 tool. Coconut leaf beetle has been infesting the country. However, primary information to the pest's ability to develop traits efficiently is still to be investigated. B. longissima metasternum was digitized and analyzed using Procrustes Analysis of Variance (ANOVA). Results have shown absence of fluctuating asymmetry between sexes and locations. Conversely, directional asymmetry and individual shape variation is evident for male and female samples in all sites. IndexTerms-Brontispa longissima, asymmetry, metasternum, procrustes ANOVA.
