Delias pasithoe, the redbase Jezebel is a medium-sized butterfly of the family Pieridae, that is, the yellows and whites. The species is found in parts of South Asia and Southeast Asia. There has been some dispute for which species the specific name aglaja (or aglaia), used twice by Linnaeus in 1758, applies – the redbase Jezebel, or the dark green fritillary (Speyeria aglaja), a brush-footed butterfly. Here, Delias pasithoe is used for the redbase Jezebel, based on the replacement name proposed by Linnaeus himself.
Upperside: black. Forewing with more or less distinct, somewhat diffuse, broad streaks from base, in the discoidal cell and interspaces 1 and 2, the streak in the last the most produced; a white oval spot at lower apex of cell traversed by the lower discocellular, followed by a subterminal series of greyish-white hastate (spear-shaped) markings with their points turned inwards, the markings opposite the apex of the wing elongate and shifted a little inwards. Hindwing: a broad subbasal transverse greyish-white band merged posteriorly in a large bright yellow dorsal patch that fills the apical two-thirds, the extreme apex excepted, of interspaces...

Likely
About 40% of wildlife watchers report a Red-Based Jezebel sighting in Hong Kong on a given day, based on 1,068 verified sightings from GBIF citizen-science data. It is the most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January and November
In those months about 60% of wildlife watchers report a Red-Based Jezebel in Hong Kong on a given day, against about 10% in June to August, the lowest months. Those are among Hong Kong's driest months, with about 35 mm of rain a month against 280 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red-Based Jezebel sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 11 cities where we can rate Red-Based Jezebel sightings, Hong Kong has the highest daily chance: about 40%. Next come Tuen Mun (China, about 30%) and Zhuhai [Macau] (China, about 30%).
GBIF citizen-science records
It is estimated from how often the Red-Based Jezebel is recorded against all the insects logged in Hong Kong (1,068 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.
