Chrysomya megacephala Sexual size dimorphism (SSD) is common in many animals including Chrysomya megacephala (blowfly) which is the subject of this study (1). SSD is the difference in size between male and female animals (1). The size differences in males and females has been proven to be intra-specific (varying ratios within species) due to the possibilities of genetics, sex difference in plasticity of body size, or maybe, environmental adaptations (1). When males and females are exposed to the same temperature, but react differently, then variation in SSD can occur [Differential-plasticity hypothesis (2)]. The hypothesis was tested by scrutinizing SSD in six populations of C. megacephala , in two different rearing temperatures [twenty degrees Celcius and thirty degrees Celcius(1)]. The taxonomic classification of C. megacephala is Kingdom Animalia, Phylum Arthropoda, Class Insecta, Order Diptera, Family Calliphoridae, Genus Chrysomya and species megacephala (3). A discusting feature of C. megacephala is that they

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
