Designing a Bioluminescent Reporter Assay: Normalization
Each firefly species has its own signaling system. In most North American species, the males fly around at the right height, in the right habitat and at the right time of night for their species, and flash a signal unique to their kind. The females are sitting on the ground or in vegetation, watching for … See more Fireflies produce light in special organs in their abdomens by combining a chemical called luciferin, enzymes called luciferases, oxygen and the fuel for cellular work, ATP. … See more Many fireflies protect themselves from predators with chemicals called lucibufagins. These are molecules the insects synthesize from other chemicals they eat in their diet. Lucibufagins are chemically very … See more Most fireflies are habitat specialists, using woodlands, meadows and marshes.
