💡 Interesting Facts

1

Case Artisans: Giant caddisfly larvae craft 5 cm silk-and-twig cases in Great Otway’s streams, filtering 100 grams of algae daily. These homes, unique to each species, protect millions, though damming threatens their pristine aquatic habitats.

2

Water Sentinels: Their presence in Mount Field’s clear rivers indicates healthy ecosystems, with larvae requiring unpolluted water to thrive. Pollution in Royal National Park’s streams endangers their populations, with conservation monitoring Tasmania’s waterways.

🔭 Sighting Guide

📍 BEST PLACES TO SIGHT

Great Otway National Park in Victoria offers Aire River and Triplet Falls streams for caddisfly sightings at dusk

Mount Field National Park in Tasmania has Russell Falls clear waterways for caddisfly sightings

Royal National Park in New South Wales features Hacking River wet areas for caddisfly sightings

🗓️ BEST TIME TO SIGHT

November-March. Wet season increases caddisfly activity near streams for mating and larval emergence.

🎯 SIGHTING TIPS

Search stream banks near Triplet Falls, Hacking River and Russell Falls at night to spot caddisflies near water.
