Fly wing morphology study with geometric morphometrics
Wings of blowfly species Chrysomya megacephala were collected and examined with Geometric morphometric (GMM) using landmark-based method. This species of Calliphoridae was chosen as it is abundant in Kelantan. The species of C. megacephala is important in forensic work as this species is commonly...

| description | Wings of blowfly species Chrysomya megacephala were collected and examined with
Geometric morphometric (GMM) using landmark-based method. This species of
Calliphoridae was chosen as it is abundant in Kelantan. The species of C. megacephala is
important in forensic work as this species is commonly found in forensic cases involving
dead bodies. The examination of wing is focused on wing venation pattern to differentiate
wing shape and wing variation between male and female flies. The total number of wings
(n = 136) of 68 flies from 12 male flies (n = 24) and 56 females fly (n = 112) were obtained
and scanned. Landmark configuration (x, y) were made on all wings and analyzed with
Principal Component Analysis (PCA). Procrustes ANOVA was utilized to detect any
measurement error by analyzing the centroid size and shape variation of sample. The
small value of the measurement error (0.2%) indicated high accuracy of landmarks
selected for this research. Sex could be easily differentiated based on the morphology of
the wings based on GMM analysis. The PC1 and PC2 from the PCA contributes to 41.5%
of the total eigenvalue scores. In conclusion, there is morphological sexual differences
between in the C. megacephala wing shape. |
