Rare
Under 5% of wildlife watchers report a Sri Lanka Weevil sighting in Everglades National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 315th most-seen of the 496 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.
April, September–October and December–January
In those months about 10% of wildlife watchers report a Sri Lanka Weevil in Everglades National Park on a given day, against under 5% in February–March, May–August and November, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sri Lanka Weevil sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Sri Lanka Weevil sightings, Everglades National Park ranks 3rd at under 5%. The best odds are in Big Cypress National Preserve (United States, about 10%) and Merritt Island National Wildlife Refuge (United States, about 10%).
Same family: Curculionidae
The closest relatives of the Sri Lanka Weevil that you can see in Everglades National Park (family Curculionidae, True Weevils) are Blue-Green Citrus Root Weevil (about 10%) and Little Leaf Notcher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sri Lanka Weevil is recorded against all the insects logged in Everglades National Park (9 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.
