Fly Metamorphosis is a Beautiful Nightmare | KQED
Briefly

The transformation from maggot to fly involves a miraculous process known as eclosion, where the fly struggles to break free from its hard casing after pupation.
Scientists at the Natural History Museum X-rayed the pupa, revealing the astonishing change from a bloated maggot to a fully formed insect with legs and wings.
The adult fly carries a ptilinal suture, a permanent reminder of its struggle to emerge from the pupa, signifying the challenges faced during transformation.
Once it escapes its casing, the fly uses hemolymph to expand its wings, marking its journey of transformation from an unassuming maggot to a flying insect.
