Sarisa is a monotypic moth genus in the family Geometridae and was first described by David Stephen Fletcher in 1979. The genus contains only one species, Sarisa muriferata, the hook-tip fern looper, which is endemic to New Zealand and surrounding islands. This species was described by Francis Walker in 1862. It is widespread in the North and South Islands, and has been recorded from Stewart Island, Big South Cape Island, the Chatham Islands and the Auckland Islands.
The genus Sarisa was first described by Fletcher in 1979. Sarisa is a replacement name for the genus Gargaphia, Walker 1863 which was preoccupied by Gargaphia, Stål, 1862. The only species in this genus, S. muriferata, was originally described by Francis Walker in 1863 and named Gargaphia muriferata. The female holotype is held at the Natural History Museum, London.
Full-grown larvae are approximately 30 mm long. Adults have functional mouthparts and are attracted to nectar sources. This species is endemic to New Zealand and its surrounding islands. The larvae are active in summer and autumn. They hide during the day in leaf litter and are active at night... Wikipedia →

With luck
About 10% of wildlife watchers report a Hook-Tip Fern Looper sighting in Egmont National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 191 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August and November
In those months about 20% of wildlife watchers report a Hook-Tip Fern Looper in Egmont National Park on a given day, against under 5% in April–July, September–October and December, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Hook-Tip Fern Looper sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
2nd of 3
Of the 3 parks where we can rate Hook-Tip Fern Looper sightings, Egmont National Park ranks 2nd at about 10%. The best odds are in Rakiura National Park (New Zealand, about 20%).
Same family: Geometridae
The closest relatives of the Hook-Tip Fern Looper that you can see in Egmont National Park (family Geometridae, Geometer Moths) are Forest Semilooper (about 20%), Oblique-Waved Fern Looper (about 20%) and Common Forest Looper (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hook-Tip Fern Looper is recorded against all the insects logged in Egmont National Park (5 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.
