The blowfly Chrysomya megacephala (Diptera: Calliphoridae) colonizes different environments and is found in many global regions. Its importance includes its involvement in the decomposition of organic matter, forensic entomology, maggot therapy, bioprospecting, source of biodiesel, industry, stabilization of heavy metals in soil, pollination, and as a vector of diseases and causing secondary myiasis. Internal morphological studies contribute to understanding insect's function and provide basic data for applied areas with interest in this specie. The objective of this study was to describe the internal morphology of C. megacephala larvae. Post-embryonic development occurred over 240 h, equally divided into larval and pupal stages. After hatching, the larvae averaged <1 mm in length and 0.02 mg in weight, growing to 13.83 mm and 50.4 mg in the third instar. We utilized whole, third-instar larvae to perform histology. Sensory organs were observed in the cephalic region, antennae, maxillary palps, and ventral organ. The alimentary canal comprises a foregut, midgut, and hindgut, including tracheal insertions and accessory organs, such as salivary glands. The midgut is the largest organ of the alimentary canal and fat body are present in body cavity and intersegmental space. Thus, our data about the internal morphology of C. megacephala larvae describe the structure and position of the alimentary canal, salivary gland, sensory organs, and fat body. [Display omitted] • Histology sections of whole larvae provided information about the internal morphology of Chrysomya megacephala. These data will be useful in understanding this blowfly, its positive and negative impacts, and its potential for human use. • Observation of sensory organs in cephalic regions, antennae, and maxillary palps alongside the alimentary canal's detailed structure enhances our understanding of the functional anatomy of C. megacephala larvae, offering valuable information for diverse disciplines, including bioprospecting and disease vector control. • Post-embryonic development of C. megacephala larvae spans 240 hours, with distinct stages and significant growth, providing insights into the developmental biology of this species crucial for research and practical applications.
