What makes a glow worm glow?

Answer 1

All glow worms glow during their larval stage. Some also glow in the adult female state.

There are three main familes of glow worms (actually beetles or flies).

* Lampyridae (Europe and Asia, usually called fireflies or lightning bugs). The wingless adult females glow with a yellow-green colored light to attract males and as a warning signal to predators (they are mildly toxic). The larvae can also emit light.

* Phengodidae (North and South America, usually called glow worm beetles) females adults glow with a yellow-green colored light to attract a mate. The larvae (usually called glow worms) also emit light.

* Arachnocampa (New Zealand and Australia) glow in their larva stage with a blue-green colored light to attract tiny insects into sticky snare lines for eating. Most of their life is spent in the larva stage. Very interesting, but you dont have to be so smarty-pants. Glow worms glow when they are larvae. There, I answered it in 7 words! LOL just jokes, you might be smarter than me, but i got a budgie and it rox ur sox!

Answer 2

Glowworm, or glow worm, is the common name for various different groups of insect larvae and adult larviform females that glow through bioluminescence. They may sometimes resemble worms, but all are insects (Arachnocampa and Orfelia being flies and all the others being beetles).

Answer 3

Glow worms are not worms at all. They are the larvae of insects that can belong to a large mosquito-like fly of the genus Arachnocampa or to beetles of the family Lapyridae.
