What organs produce light in bioluminescent chironomid midges?

Explanation:
In bioluminescent chironomid midges, light comes from specialized photogenic lanterns in the abdomen that are derived from Malpighian tubules. These excretory tubes have been modified to host photocytes that produce light through the luciferin–luciferase system, with nerves or hormones controlling when the flashes occur to attract mates. The midgut, fat body, and oenocytes perform digestive or metabolic roles and do not form the light-emitting tissues in this group, making the Malpighian tubules the tissue of origin for their glow.
