Attracted to UV light.
I found another one! https://inaturalist.nz/observations/149342374 @dave_holland @leigh_winsor
The remainder of some moths I recorded at night in the Catlins Forest 12 days ago
amaaaaaazing, what the heck is this. Very long (at least as long as my Nalgene bottle, 21cm), thin, fluro-green planarian. Seems to be at least one prior observation, but identification didn't get very far: https://inaturalist.nz/observations/9506116
