Phengodidae (plural form) (noun)
The scientific name for a beetle whose larvae are glowworms so named for the bioluminescent qualities among the females: The farmer said that there must have been a great number of the families of the Phengodidae in the woods recently because he had seen so many glowworms.

The beetle family Phengodidae is also known as "glowworm beetles" or "glowworms"

Larval and larviform female glowworms are predators, feeding on millipedes and other arthropods that exist in soil and litter. The winged males, which are often attracted to lights at night, live for a short time and probably do not feed.

Females are much larger than the males and are completely larviform. Males may be luminescent, but females and larvae have a series of luminescent organs on their trunk segments which produce yellow or green light, and sometimes an additional head organ which exhibits red light, as in "railroad worms".
