Rare
Under 5% of wildlife watchers report an Alder Spittlebug sighting in Chicago on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 473rd most-seen of the 978 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 Alder Spittlebug in Chicago on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Alder Spittlebug sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Alder Spittlebug is recorded against all the insects logged in Chicago (17 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.
