Callionima denticulata
In 3 days ~20% in a week ~40%
Callionima denticulata is a species of moth in the family Sphingidae, which is known from Panama, Mexico, Costa Rica, Nicaragua, Bolivia, Peru and western Venezuela. It was originally described by Schaus as Calliomma denticulata, in 1895.
The wingspan is 59–72 mm. Adults are on wing year round in Costa Rica. It is extremely similar to Callionima pan pan, but the forewing apex is strongly truncate, the outer margin strongly excavate below the apex and markedly dentate. The basal half of the forewing underside is distinctly orange, contrasting with the greyish-brown distal part. The hindwing upperside is as in Callionima pan pan, but the black anal spot is at least 1.5 mm wide.
The larvae feed on Tabernaemontana alba and probably other Apocynaceae species. They are green with reddish orange spiracles and a longitudinal, dotted black line down the back and an orange, thick anal horn. Wikipedia →

With luck
About 10% of wildlife watchers report a Callionima denticulata sighting in Monteverde Cloud Forest Reserve on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 215th most-seen of the 506 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.
November
In that month about 20% of wildlife watchers report a Callionima denticulata in Monteverde Cloud Forest Reserve on a given day, against under 5% in June and December–March, the lowest months. That is one of Monteverde Cloud Forest Reserve's wettest months, with about 320 mm of rain against 45 mm in March.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Callionima denticulata sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Callionima denticulata sightings, Monteverde Cloud Forest Reserve has the highest daily chance: about 10%. Next come Tapantí-Macizo de la Muerte National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Callionima denticulata is recorded against all the insects logged in Monteverde Cloud Forest Reserve (13 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.
