Libellago is a genus of damselflies in the family Chlorocyphidae. It is the only genus in the subfamily Libellagininae. Species of Libellago are found mainly in Southeast Asia. Selys established the genus Libellago in 1840, in his Monographie des libellulidées d'Europe, as one of two new non-European genera separated from Calopteryx. In 1853, he established the "Legion Libellago", a group of damselflies centred on the genus.
The subfamily name Libellagininae was introduced by Bianchi in 1905, in the work published jointly with Jakobson. Laidlaw proposed the subfamily Libellaginae in 1917, and subsequent authors also used the names Libellagini and Libellaginidae at tribal and family rank, respectively. The name Libellaginidae was formerly applied more broadly to the damselflies now placed in Chlorocyphidae.
In modern classifications, Libellagininae is recognised as a subfamily of Chlorocyphidae, comprising only the genus Libellago. The following are included in BioLib.cz: Genus Libellago of Borneo Wikipedia →

With luck
About 10% of wildlife watchers report an Ebony Gem sighting in Sinharaja Forest Reserve on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 77th most-seen of the 117 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.
March and August–September
In those months about 30% of wildlife watchers report an Ebony Gem in Sinharaja Forest Reserve on a given day, against under 5% in April–July and October–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Ebony Gem 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 Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Ebony Gem sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ebony Gem is recorded against all the insects logged in Sinharaja Forest Reserve (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.
