Pycnarmon leucinodialis is a moth in the family Crambidae described by William Schaus in 1912. It is found in Costa Rica. The wingspan is about 21 mm. The wings are semihyaline iridescent white, the forewings have a more thickly scaled costal margin. There is a brownish streak on the costa towards base and two short streaks in the cell below it, as well as a white line on the discocellular, edged with pale brown. The outer line is fuscous and broad and the marginal area is shaded with light brown, except on the costa at the apex. The hindwings have a brownish shade on the discocellular, followed by some dark points. There is a subterminal fuscous line, which is more heavily marked on the costa and inner margin. The termen is more heavily scaled and silvery white. Wikipedia →

With luck
About 10% of wildlife watchers report a Pycnarmon leucinodialis sighting in Monteverde Cloud Forest Reserve on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 66th most-seen of the 506 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Pycnarmon leucinodialis in Monteverde Cloud Forest Reserve on a given day, against under 5% in December, the lowest month.

Across all the parks we cover, that three-hour window holds the most Pycnarmon leucinodialis sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Monteverde Cloud Forest Reserve, in our data
Monteverde Cloud Forest Reserve is the only park on Wallace's Line with enough records to rate Pycnarmon leucinodialis sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Pycnarmon leucinodialis is recorded against all the insects logged in Monteverde Cloud Forest Reserve (38 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.
