Delta esuriens
In 3 days ~60% in a week ~80%
Delta esuriens is a species of potter wasp found in tropical Asia, belonging to the Vespidae family. They can be separated from the similar looking Delta pyriforme by the presence of a yellow band on the metasomal petiole segment.
Female Delta esuriens build a nest of mud with 1-8 cells adjacent to each other in 1 or 2 rows with their entrance holes pot-like which are provisioned with lepidopteran caterpillars before an egg is laid and the entrance hole sealed. The egg hangs from the cell wall, suspended by a bit of silk. About 3 to 10 caterpillars may be placed in a single cell. The eggs hatch in a couple of days and feed for a week. Pupation takes about two weeks. Male offspring have a slightly shorter development time and emerge earlier. The adults emerge from the cells in about a month. The larvae are parasitized by Chrysididae and Bombyliidae and preyed on by Sarcophagidae and ants. Wikipedia →

Possible
About 20% of wildlife watchers report an Okinawa Mud Wasp sighting in Phnom Penh on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 22 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
January, July–August and October
In those months about 40% of wildlife watchers report an Okinawa Mud Wasp in Phnom Penh on a given day, against under 5% in February–June and November–December, the lowest months.
Yes
Of the 17 cities where we can rate Okinawa Mud Wasp sightings, Phnom Penh has the highest daily chance: about 20%. Next come Naha (Japan, about 20%) and Ho Chi Minh City (Vietnam, about 10%).
Same order: Hymenoptera
The closest relatives of the Okinawa Mud Wasp that you can see in Phnom Penh (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Asian Weaver Ant (about 40%), Red Dwarf Honey Bee (about 30%) and Yellow-Sided Carpenter (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Okinawa Mud Wasp is recorded against all the insects logged in Phnom Penh (5 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.
