With luck
About 10% of wildlife watchers report a Cricula Silkmoth sighting in Jakarta on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 239 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.
June
In that month about 20% of wildlife watchers report a Cricula Silkmoth in Jakarta on a given day, against under 5% in April and August–January, the lowest months. That is one of Jakarta's driest months, with about 90 mm of rain against 370 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Cricula Silkmoth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Cricula Silkmoth sightings, Jakarta ranks 3rd at about 10%. The best odds are in Tasikmalaya (Indonesia, about 20%) and Bandung (Indonesia, about 20%).
GBIF citizen-science records
It is estimated from how often the Cricula Silkmoth is recorded against all the insects logged in Jakarta (13 verified sightings), 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.
