Polistes jokahamae
In 3 days ~30% in a week ~60%
The dark-waisted paper wasp, (Polistes jokahamae) is a species of primitively eusocial paper wasp from Southeast Asia. The dark-waisted paper wasp is found in Japan (excepting the island of Hokkaido), China, India, and Vietnam.
Queens emerge from diapause in late March. New nests are founded from mid-April to early May. Nests most often have a single founding queen; multiple foundresses are found in less than 1% of P. jokahamae colonies. Like other Polistes wasps, the dark-waisted paper wasp constructs nests of chewed plant fibers mixed with proteinaceous oral secretions.
Nests consist of multiple cells in which the queen lays her eggs. The cells are then capped with a silky material produced by the queen and the larvae develop inside. The first brood are fed and cared for by the queen. Two larvae are raised in each cell in the first brood (presumably to conserve resources) and the workers emerge smaller than those from later broods.
The first worker emerge in the summer, followed by a second brood which includes gynes (potential future queens) and a third brood which includes males. Rarely, males may be produced earlier in the colonies' lifecycle... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dark-Waisted Paper Wasp is recorded against all the insects logged in Xiamen City (7 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.
