Delta esuriens
In 3 days ~10% in a week ~30%
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 →

Rare
Under 5% of wildlife watchers report an Okinawa Mud Wasp sighting in Chennai on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 338th most-seen of the 376 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report an Okinawa Mud Wasp in Chennai on a given day, against under 5% in September to July, the lowest months.
14th of 17

GBIF citizen-science records
It is estimated from how often the Okinawa Mud Wasp is recorded against all the insects logged in Chennai (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.
