The O’Reilly’s Experience
What does it truly feel like to descend upon O’Reilly’s Glow Worm grotto
on an evening guided tour?
Journalist Celeste Gill recounts:
We’re walking single file, torches to the ground to ensure we place one foot in front of the other and don’t slip into the creek. I can vaguely see my breath dancing in the cool night air in front of my face. The sounds of the rainforest surround us between the crackling of leaves and twigs beneath our feet.
“Okay, turn off your torches,” our guide Martin says. “They don’t like the light.” It takes a few seconds for my eyes to adjust, but then we see them; spread out before us like a blanket of fireflies, their glow slowly becomes brighter, and brighter. There must be thousands of them. It’s like a miniature Milky Way clutching at the bushes that line the creek.
“Luminescent larvae” is a sexy name for Glow Worms. “In reality they’re more like glow maggots,” Martin says.
Regardless of the name, these tiny creatures add an extra sprinkle of magic to the night in Lamington National Park.
Glow Worm Development
Put simply, Glow Worms are the larvae (or immature stage) of a small fly’s development. Interestingly, this larval stage is the only time in their life cycle in which they glow in order to attract small insects to feed.
Larvae are believed to live for approximately one year, by capturing their prey on snares – a sticky silk thread much similar to a spider’s web. Their famed predatory light in which they produce lures prey closer, tricking them into becoming entangled in the larvae’s silken threads. Once developed into adulthood, the flies unfortunately do not have working mouthparts, and therefore only live for two days to six days during which time they mate and lay eggs before perishing (and the life cycle continues).
