Insects Come Alive in Insect Cartoons, Insect Animations, Insect Sounds, and Insect Facts.
Fireflies emit light by the oxidation of luciferin.
The animated firefly image shows the light coming from a firefly. There is a serious challenge for heaviest insect in the world in the form of the New Zealand, True Wetas, for instance a gravid female Deinacrida heteracantha can weigh as much as 70 grams. Another competitor for the title is the extremely rare South American Longhorn Beetle Titanus giganteus . These giants can be over 16cms in body length, not including the antennae. Other longhorn beetles are nearly as long and may look bigger because of their longer legs like the Xixuthrus heros from Fiji.
