Chrysodeixis eriosoma, the green garden looper, known in New Zealand as the Silver Y, is a moth of the family Noctuidae. Mostly cosmopolitan in distribution, it is a pest in Japan, China, India, Sri Lanka, the Malay Peninsula and Australasia. It is present in Hawaii and recorded as an incursion in mainland North America and Russia. It is morphologically identical to Chrysodeixis chalcites and the two may be sibling species.
Chrysodeixis eriosoma has a wingspan of 42 mm. Some specimens are much darker than others. Chrysodeixis eriosoma differs from C. signata in the head, thorax, and forewing having a reddish tinge; abdomen with the lateral and anal tufts often black in the male. Forewing with much more gilding on the basal, medial, and outer areas; the antemedial line more oblique, the postmedial more oblique and sinuous; the Y mark large, prominent, and golden, the arms often filled in with golden and occasionally joined to the tail.
Chrysodeixis eriosoma and Chrysodeixis chalcites moths cannot be separated morphologically, and they may be sibling species. However, they may be distinguished based on DNA sequencing, pheromones, or geographic origin as... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green Garden Looper sighting in Hong Kong on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 648th 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.
January, April and October
In those months about 10% of wildlife watchers report a Green Garden Looper in Hong Kong on a given day, against under 5% in February–March, May–September and November–December, the lowest months. Those are among Hong Kong's driest months, with about 65 mm of rain a month against 280 mm in June.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Green Garden Looper sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
5th of 8
Of the 8 cities where we can rate Green Garden Looper sightings, Hong Kong ranks 5th at under 5%. The best odds are in Auckland (New Zealand, about 10%), Tuen Mun (China, under 5%) and Perth (Australia, under 5%).
Same family: Noctuidae
The closest relatives of the Green Garden Looper that you can see in Hong Kong (family Noctuidae, Cutworm Moths and Allies) are Flammona trilineata (about 10%), Oriental Leafworm Moth (about 10%) and Cerynea discontenta (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Garden Looper is recorded against all the insects logged in Hong Kong (13 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.
