Rare
Under 5% of wildlife watchers report a Condylostylus longicornis sighting in Galápagos Islands on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 83 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.
June–July and December
In those months about 10% of wildlife watchers report a Condylostylus longicornis in Galápagos Islands on a given day, against under 5% in January–May and August–November, the lowest months. Those are among Galápagos Islands's driest months, with about 5 mm of rain a month against 50 mm in March.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Condylostylus longicornis sightings with a recorded time, and nearly all 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 Condylostylus longicornis sightings, Galápagos Islands ranks 3rd at under 5%. The best odds are in Ría Lagartos Biosphere Reserve (Mexico, about 10%) and Everglades National Park (United States, about 10%).
Same order: Diptera
The closest relatives of the Condylostylus longicornis that you can see in Galápagos Islands (order Diptera, Flies) are Toxomerus crockeri (about 10%) and Tabanus vittiger (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Condylostylus longicornis is recorded against all the insects logged in Galápagos Islands (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.
