Generally blowfly maggots in New Zealand have to feed on animal tissue or faeces to develop into adult blowflies. However the New Zealand blue blowfly larvae can survive on decaying leaves of snow tussock in alpine regions and reach adult maturity without feeding on any animal tissue.
The blue blowfly larvae are made up of a head, three thoracic segments and eight abdominal segments. The head is often so small it is hidden in the thoracic segment, and it has two lobes, a pair of antennae and also a pair of maxillary palps (bristle-like hairs attached to the mouthparts) that serve as an additional sensory structure. The mouth is situated at the lower front part of the head and has a pair of hardened mouth hooks. The oral sclerite in Calliphora quadrimaculata is short compared to other species in the same family. On the first thoracic segment is a pair of... Wikipedia →

With luck
About 10% of wildlife watchers report a New Zealand Blue Blowfly sighting in Fiordland National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 201 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
August–September and December–February
In those months about 20% of wildlife watchers report a New Zealand Blue Blowfly in Fiordland National Park on a given day, against under 5% in May–July and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most New Zealand Blue Blowfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate New Zealand Blue Blowfly sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Diptera
The closest relatives of the New Zealand Blue Blowfly that you can see in Fiordland National Park (order Diptera, Flies) are New Zealand Glowworm (about 20%), Large Hover Fly (about 10%) and Rhamphophila sinistra (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the New Zealand Blue Blowfly is recorded against all the insects logged in Fiordland National Park (22 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
