Generally found on meat, rotten logs, carrion, human feces, fish , garbage dumps etc. The term “Old World blow fly” is a derivative of both the associated family, Calliphoridae, and the belief that the genus Chrysomya originated in Asia and migrated to North America only relatively recently. Pairwise comparison of centroid sizes between sampling intervals indicated the shape mostly transformed during early developmental stages (Table 2). This technique was previously employed in distinguishing insect species and sex, including forensically important blow flies which were attributed by the wing landmarks (Nuñez-Rodiguez and Liria 2017a; Nuñez and Liria 2017b; Sontigun et al.

The ontogenetic allometry, i.e., the relationship between size and shape across different ages, and visualization of landmark dispositions were also performed by using prescribed methods (Klingenberg 2013; Mitteroecker et al. The developmental period of C. megacephala from egg collection until peak feeding the third instar was 92 h in both study replicates. C. megacephala's eggs are "oval with one flat face and another convex". (1940). A textual diagnostic description of the species that is not necessarily structured.

Due to the allometric effect, we reran cross-validation test on the groups without the effect of size on the morphological changes by using residuals from multivariate regression analysis (Klingenberg 2016). Like the American screwworm, this species is attracted to dry, open wounds as well as to most body openings. Eur J Entomol 110(3):461–468. The two-dimensional images were then converted to a readable format using tpsUtil (version 1.74) and landmarks were plotted by using tpsDig2 (version 2.31) (download link: http://life.bio.sunysb.edu/morph/). By using regression analysis of the Procrustes coordinates and centroid size/log-transformed centroid size, the association between shape and size across different age groups was significant with moderate to high effect. The most abundant species was C. megacephala (57.71%) followed by C. albiceps (41.94%) and Chrysomya putoria (Wiedemann, 1830) (0.35%). Files are available under licenses specified on their description page. Geometric morphometric analysis of cephalopharyngeal skeleton was carried out by using MorphoJ software (Klingenberg 2011) (download link: http://www.flywings.org.uk/morphoj_page.htm_), which includes visualization of landmark shifts and canonical variate analysis (CVA) to provide graphical ordination of individuals and groups in multidimensional space, followed by cross-validation test in discriminant function analysis (DFA) to classify individuals in separate groups. Images of cephalopharyngeal skeleton were obtained directly after specimen mounting by using a stereomicroscope (Nikon, Japan) fitted with a 12-megapixel USB3.0 CMOS microscope camera (Toupcam, China). Through visual assessment of these five landmarks on C. megacephala larval development, transformation occurred at all landmarks with the least change on landmark 3 (the concavity of pharyngeal sclerite or medial incision). This research was funded by UKM Research Incentive Grant: GGP-2017-036.

Chrysomya megacephala (Fabricius) is a well‐known blow fly species of medical importance worldwide. Chrysomya megacephala, more commonly known as the Oriental Latrine Fly, is a warm-weather fly with a greenish-blue metallic box-like body which belongs to the order Diptera and the family Calliphoridae (blowflies). The cephalopharyngeal skeleton shape was profiled based on centroid size, i.e., the square root of the sum of squared distances between each landmark and the centroid of the cephalopharyngeal skeleton (Zelditch et al. Correlations between centroid size and cephalopharyngeal skeleton developmental time were determined by using Pearson’s correlation test. https://doi.org/10.1111/j.1755-0998.2010.02924.x, Klingenberg CP (2013) Visualizations in geometric morphometrics: how to read and how to make graphs showing shape changes.

The alimentary canal is a major organ system that is often involved in the transmission of pathogens to humans from insects that serve as vectors of disease. Chrysomya megacephala (F.) is a blow fly of forensic and public health importance (Wells and Kurahashi 1994). C. putoria is native to Africa and has recently spread to the Americas.
