Paederus fuscipes
In 3 days ~30% in a week ~50%
Paederus is a genus of small beetles of the family Staphylinidae ("rove beetles"). With 622 valid species assigned by 1987 to the subtribe Paederina (Paederus and its close allies), and with all but 148 within Paederus itself, this is a large genus.
Due to toxins in the hemolymph of some species within this genus, it has given its name to paederus dermatitis, a characteristic skin irritation that occurs if one of the insects is crushed against skin. A scholarly paper in 2002 suggested that a Paederus species could have been responsible for some of the ten Plagues of Egypt described in the Bible's Book of Exodus.
Paederus species are widely distributed around the world. Paederus species are much more brightly colored than most other rove beetles, with metallic blue- or green-colored elytra and many with bright orange or red on the pronotum and the basal segments of the abdomen. These bright colors may be an example of aposematism, a warning signal to potential predators.
Although most adult rove beetles avoid daylight, Paederus species are active during the day and attracted to bright lights after nightfall. Paederus eggs are laid singly, in moist habitats... Wikipedia →

With luck
About 10% of wildlife watchers report a Paederus fuscipes sighting in Hangzhou on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 172 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March, May–July and September–November
In those months about 10% of wildlife watchers report a Paederus fuscipes in Hangzhou on a given day, against under 5% in April, August and December–February, the lowest months.
Yes
Of the 9 cities where we can rate Paederus fuscipes sightings, Hangzhou has the highest daily chance: about 10%. Next come Taichung (Taiwan, about 10%) and Beijing (China, about 10%).
Same order: Coleoptera
The closest relatives of the Paederus fuscipes that you can see in Hangzhou (order Coleoptera, Beetles) are Asian Lady Beetle (about 30%), Titan Stag Beetle (about 20%) and Adam's Stag-Horned Beetle (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Paederus fuscipes is recorded against all the insects logged in Hangzhou (14 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.
