Zelandoperla fenestrata is a widespread endemic New Zealand ‘long-tailed’ stonefly that is often abundant in high-gradient stony streams, from near sea-level up to alpine elevations. [1] The species name 'fenestrata' refers to the window-like rectangular patterning visible on the wings of non-melanic adult specimens.

For instance, the New Zealand black stonefly Austroperla is a forest dwelling shredder that is toxic to predators due to its production of hydrogen cyanide. [4] The warning colouration of this species is mimicked by several lineages of the unrelated non-toxic New Zealand stonefly Zelandoperla .
The colouring can vary, and subtle patterns are occasionally found on the abdomen. They are detritivores , eating stream debris partially broken down by other organisms. They are "shredders" as a functional feeding group, breaking down large bits of detritus down into smaller ones while feeding. [ 2 ]
