Caddisfly nymph (Genus Polyplectropus) Net-spinning caddisfly
Subclass: Pterygota (caddisflies)
Common name: Net-spinning caddisfly, Caseless caddisfly
Caddisflies in the genus Polyplectropus are called tube makers. Polyplectropus caddis larvae have no mobile case, no chelae (pincers) and they have a distinctly speckled head pattern. The head pattern does not include a curved line of spots. The larvae are common throughout New Zealand in slow-flowing gravely streams or soft bottom streams with woody debris,
They construct delicate, silk, filter-feeding nets to trap drifting particulate food items, including other invertebrates and plant fragments.
