In 3 days ~10% in a week ~20%
Acosmeryx shervillii, the dull forest hawkmoth, is a moth of the family Sphingidae. The species was first described by Jean Baptiste Boisduval in 1875. It is found from the Indian subregion, Sri Lanka, to Sundaland, the Philippines and Sulawesi. Acosmeryx pseudonaga is sometimes treated as a valid species.
The colour varieties of the species have been described as separate species many times. However, they are classified as colour morphs of the single species A. shervillii. According to The Fauna of British India, Including Ceylon and Burma: Moths Volume I by G. F. Hampson:
Greyish brown; the vertex of head dark; pro-, meso-, and meta- thorax each with a dark transverse streak; dorso-lateral oblique dark stripes on each segment of the abdomen. Fore wing with nine curved and waved antemedial dark lines, the interspaces between three of the pairs of lines being filled in with dark brown, so as to form one subbasal and two antemedial bands; a dark-ringed pale speck at end of cell, the pale center being sometimes obsolete; four postmedial curved lines; an oblique dark band from beyond the middle of the costa to outer angle, in some of the forms produced outwards along...

Rare
Under 5% of wildlife watchers report an Acosmeryx pseudonaga sighting in Hong Kong on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 925th 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.
April
In that month about 10% of wildlife watchers report an Acosmeryx pseudonaga in Hong Kong on a given day, against under 5% in May to March, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Acosmeryx pseudonaga sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Acosmeryx pseudonaga sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Acosmeryx pseudonaga is recorded against all the insects logged in Hong Kong (6 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.
