of the light produced. Measuring it? Not easy. They had to hold the insects since they won’t glow in captivity. They discovered that the light-emitting portion of the fly’s body is made up of numerous small scintillating points like viewing fireflies on a summer’s eve. (2 of 3)

Week 9 - Firefly Luminous Efficiency

This technical report is a unique intersection of biology and physics, and one of TRAIL’s most delightful reports.

This research into the light emitted by fireflies – or lightening bugs was conducted to determine the energy level... (1 of 3)
