Puriri Moth

New Zealand's largest moth, with a wingspan up to 150 mm. The caterpillars bore into the trunks of native trees, particularly puriri and putaputaweta, creating characteristic U-shaped tunnels. Adults have no functional mouthparts and do not feed.

Puriri moth larvae can spend up to six years boring through living tree trunks before pupating and emerging as adults that live only a few days.

South African Alderfly

One of the few alderfly species found in the Southern Hemisphere, occurring in clean mountain streams of South Africa. Adults are small with dark wings.
