Surprisingly, a springtail expert on iNaturalist has suggested a species ID for this springtail. I wasn't expecting it to be able to be identified to that detail, but it certainly matches the description. It looks like it's *Bourletiella arvalis*.
That makes the springtail a lot more interesting than the moth it's on.
The Global Biodiversity Information Facility (#GBIF) has 334 observations of the moth species (178 of which are from iNaturalist).
GBIF has only 16 observations of this springtail species from New Zealand. If confirmed, my little hitch-hiker here will be the 17th.
