Arhopalus ferus
In 3 days ~30% in a week ~60%
Arhopalus ferus, commonly known as the burnt pine longhorn beetle, is a species of long horn beetle, of the order Coleoptera. It was first described by French entomologist Étienne Mulsant in 1839. Adult beetles are 8–30 mm long reddish-brown to black, while males are generally smaller and lighter in colour.
The body is elongated and oval, typical for longhorn beetles. The head angles forward, showing most of the mouth parts. The thread-like antennae are half to three-quarters of the body length, longer in males. The prothorax is smoothly curved with no spines, narrower than the elytra. The elytra have four ridges and slightly tapering sides.
Eggs are white, opaque, and cigar-shaped, measuring about 0.5 by 1.8 mm. Creamy white larvae are cylindrical, with noticeable legs and pointed jaws. Larvae are active when removed from their tunnels. Arhopalus ferus prefers dead or dying Pinus and Picea injured by fire or other damage but rarely it will develop in healthy trees. Females are attracted to volatiles from burnt trees or sawmills.
Adults, live for several weeks, and emerge in spring to autumn. Females can lay up to about 1000... Wikipedia →

With luck
About 10% of wildlife watchers report a Burnt Pine Longhorn sighting in Abel Tasman National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 64 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January and March
In those months about 20% of wildlife watchers report a Burnt Pine Longhorn in Abel Tasman National Park on a given day, against under 5% in April to November, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Burnt Pine Longhorn sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Abel Tasman National Park, in our data
Abel Tasman National Park is the only park on Wallace's Line with enough records to rate Burnt Pine Longhorn sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Burnt Pine Longhorn is recorded against all the insects logged in Abel Tasman National Park (10 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.
