Blowfly maggot pupa, SEM
Blowfly pupa on carpet. Coloured scanning electron micrograph (SEM) of a Calliphora vicina blowfly pupa that will hatch an adult fly. A blowfly lays its eggs on dead bodies. This behaviour is studied by forensic entomologists. Eggs generally hatch within 24 hours. A Calliphora larva (maggot) feeds on the decaying flesh for 2-3 weeks. It then moves to a dark place to avoid predation as it pupates. It lies dormant in its pupa, and slowly develops into the adult winged form. A pupa can survive fumigation and other hostile environments. The hatching (by incubation) of pupae found by a dead body can help in estimating the time of death. Magnification unknown

EDITORS COMMENTS
This print captures the intricate beauty of a blowfly maggot pupa, showcasing its vibrant colors and unique texture. In this coloured scanning electron micrograph (SEM), we witness a Calliphora vicina blowfly pupa resting on a carpet, symbolizing the fascinating world of nature's cycle. Blowflies are known for their peculiar behavior of laying eggs on deceased bodies, making them subjects of interest for forensic entomologists. Within 24 hours, these eggs hatch into larvae or maggots that feed on decaying flesh for several weeks. As they reach maturity, they seek refuge in dark places to avoid predators and undergo metamorphosis into pupae. The dormant stage within the pupa is crucial as it gradually transforms into an adult winged fly. Remarkably resilient, these pupae can withstand fumigation and hostile environments while preserving vital information about decomposition processes. In crime research and forensic entomology, hatching these discovered pupae through incubation plays a significant role in estimating time of death. By studying magnified images like this one under unknown levels of magnification using SEM technology, scientists gain valuable insights into insect behavior and contribute to solving complex cases. This extraordinary photograph not only showcases the wonders of zoology but also highlights the interconnectedness between life and death in our natural world. It serves as a reminder that even in seemingly mundane settings like carpets or floors, there exists an entire ecosystem waiting to be explored by curious minds dedicated to unraveling nature's mysteries.
