Rare
Under 5% of wildlife watchers report an Encelia Leaf Beetle sighting in Saguaro National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 229th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February–March and October–December
In those months about 10% of wildlife watchers report an Encelia Leaf Beetle in Saguaro National Park on a given day, against under 5% in January and April–September, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Encelia Leaf Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Encelia Leaf Beetle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Encelia Leaf Beetle is recorded against all the insects logged in Saguaro National Park (8 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.
