About 10% of wildlife watchers report a Megacyllene acuta sighting in Iguazú National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 248th most-seen of the 306 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Megacyllene acuta sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Iguazú National Park, in our data
Iguazú National Park is the only park on Wallace's Line with enough records to rate Megacyllene acuta sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Megacyllene acuta is recorded against all the insects logged in Iguazú National Park (6 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.
