Rare
Under 5% of wildlife watchers report an Alfalfa Leaf Tier sighting in Brisbane on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 981st most-seen of the 1083 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Alfalfa Leaf Tier in Brisbane on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Alfalfa Leaf Tier sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Alfalfa Leaf Tier sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Alfalfa Leaf Tier is recorded against all the insects logged in Brisbane (5 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.
