The camera had a hard time picking them up, because I didn't read the directions.....
Glow worms are born in bunches of between 20 and 30. As soon as the first one hatches, it begins running around and eating the other eggs. They're definitely cannibals. As soon as all of the eggs either hatch or are eaten, the offspring then begin to weave a hammock for them to live in. Once that happens, they begin to weave "tripwires." Similar to spiders, they create webs, except these drop straight down and are coated with a type of contact poison. The tails of the glow worms "glow," which I'm assuming is where the name comes from, and it attracts insects, like mosquitoes and such that come in on the river. They fly up towards the light and are caught in the tripwires. The glow worms slide down and devour the captives. This goes on for 9 months until the worms build a cocoon and emerge as a fly. The fly has a mouth that doesn't work and no stomach. They live for three days, only to breed. The female fly glows with a different color so the males know where to go, and then they die. The cycle then repeats.
