Rare
Under 5% of wildlife watchers report a Fruit Tree Borer sighting in Melbourne on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December and January
In those months about 10% of wildlife watchers report a Fruit Tree Borer in Melbourne on a given day, against under 5% in February to November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Fruit Tree Borer 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.
Yes
Of the 3 cities where we can rate Fruit Tree Borer sightings, Melbourne has the highest daily chance: under 5%. Next come Brisbane (Australia, under 5%) and Sydney (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Fruit Tree Borer is recorded against all the insects logged in Melbourne (25 verified sightings), 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.
