This looks uncomfortable!
Philip Summerhays on #iNaturalistNZ took these images this evening of an apple looper moth in Auckland with its head covered in mites.
Philip writes that the moth flew away after being photographed, unharmed. I suspect the moth is incapable of moving its legs to a position where it could dislodge all these mites from its head. I don't know yet whether they're hitching a ride between flowers or feeding on the moth.
