Rare
Under 5% of wildlife watchers report an Oleander Scale sighting in San Francisco on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 679th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Oleander Scale in San Francisco on a given day, so our monthly data shows no clear season.
Only San Francisco, in our data
San Francisco is the only city on Wallace's Line with enough records to rate Oleander Scale sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hemiptera
The closest relatives of the Oleander Scale that you can see in San Francisco (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Large Milkweed Bug (about 10%), Oleander Aphid (about 10%) and Small Milkweed Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oleander Scale is recorded against all the insects logged in San Francisco (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.
