railroad worm การใช้

The " railroad worm " name arises because these glowing spots along the body resemble the windows of train cars internally illuminated in the night.
The larvae of railroad worms ( " Phrixothrix " ) have paired photic organs on each body segment, able to glow with green light; these are thought to have a defensive purpose.
Males may be luminescent, but females and larvae have a series of luminescent organs on trunk segments which emit yellow or green light, and sometimes an additional head organ which emits red light, as in railroad worms.
A "'railroad worm "'is a larva or larviform female adult of a beetle of the genus " "'Phrixothrix " "'in the family Phengodidae, characterized by the possession of two different colors of bioluminescence.
