In 3 days ~10% in a week ~20%
Toxorhynchites (Toxorhynchites) splendens is a species of non-hematophagous (not blood-feeding) mosquito belonging to the genus Toxorhynchites. It is widely used as a predator to control dengue mosquitoes. It shows nearly a cosmopolitan distribution throughout the Old World, except African continent both through human influences and natural methods. It is found in India, Sri Lanka Malaysia, Thailand, New Guinea, Fiji Islands, Philippines, Rotuma Island.
The large expansion may be due to naval transport of larva from one place to another. In 1934, these mosquitoes were introduced to Fiji as a method of biological control of Aedes polynesiensis, and in India and Malaysia to control Aedes aegypti and Aedes albopictus who are prominent vectors of many human diseases. They prefer to consume eggs and larva Aedes aegypti and Anopheles stephensi.
Alphamethrin, deltamethrin, Malathion can be used to control the mosquito. Laboratory evaluation of Toxorhynchites splendens (Diptera: Culicidae) for predation of Aedes albopictus mosquito larvae. OBSERVATIONS ON TOXORHYNCHITES SPLENDENS

Rare
Under 5% of wildlife watchers report a Toxorhynchites splendens sighting in Hong Kong on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 778th most-seen of the 1125 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.
August and September
In those months about 10% of wildlife watchers report a Toxorhynchites splendens in Hong Kong on a given day, against under 5% in October to July, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
2nd of 2
Of the 2 cities where we can rate Toxorhynchites splendens sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Toxorhynchites splendens is recorded against all the insects logged in Hong Kong (9 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.
