With luck
About 10% of wildlife watchers report a Spider Longhorned Beetle sighting in Everglades National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 255th 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.
May and December–March
In those months about 10% of wildlife watchers report a Spider Longhorned Beetle in Everglades National Park on a given day, against under 5% in April and June–November, the lowest months. Those are among Everglades National Park's driest months, with about 70 mm of rain a month against 240 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Spider Longhorned Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 parks where we can rate Spider Longhorned Beetle sightings, Everglades National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Manuel Antonio National Park (Costa Rica, about 10%) and Braulio Carrillo National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Spider Longhorned Beetle is recorded against all the insects logged in Everglades National Park (11 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.
