Rare
Under 5% of wildlife watchers report a Mangrove Dwarf sighting in Singapore on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 788th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mangrove Dwarf in Singapore on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Mangrove Dwarf sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Mangrove Dwarf sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Libellulidae
The closest relatives of the Mangrove Dwarf that you can see in Singapore (family Libellulidae, Skimmers) are Common Parasol (about 40%), Crimson Marsh Glider (about 30%) and Scarlet Skimmer (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mangrove Dwarf is recorded against all the insects logged in Singapore (8 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.
