In 3 days ~10% in a week ~20%
Pratapa deva, the white royal, is a lycaenid or blue butterfly found in the Indomalayan realm. The species was first described by Frederic Moore in 1857. Male. Upperside blue, with a mauve tint. Forewing with the median, the basal part of vein 3 and the sub-medians black, the apical black baud very broad, occupying more than a third of the wing, its inner margin rounded, narrowing gradually on the outer margin, the band near the hinder angle being fairly broad, on the costa it rapidly narrows, the basal third quite narrow. Hindwing with the costa broadly black, bulging hindwards below the glandular patch of scales; a narrow outer marginal black band; some blackish suffusion along the abdominal area, the fold grey; the marginal band ending in black spots in the three anal interspaces; tails black, tipped with white. Cilia black, with pale tips. Underside cream colour; a series of very thin discal, disconnected, brown linear marks across both wings, generally obsolescent on the forewing, curving round to the abdominal margin a little above the anal angle on the hindwing, the tuft of hairs attached to that portion of the inner margin of the forewing which is strongly...

Rare
Under 5% of wildlife watchers report a White Royal sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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.
February
In that month about 10% of wildlife watchers report a White Royal in Hong Kong on a given day, against under 5% in March to January, the lowest months. That is one of Hong Kong's driest months, with about 30 mm of rain against 280 mm in June.
Yes
Of the 2 cities where we can rate White Royal sightings, Hong Kong has the highest daily chance: under 5%. Next come Singapore (Singapore, under 5%).
Same family: Lycaenidae
The closest relatives of the White Royal that you can see in Hong Kong (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Plains Cupid (about 20%) and Abisara echeria (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White Royal is recorded against all the insects logged in Hong Kong (11 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.
