Homona coffearia, the tea tortrix or camellia tortrix, is a moth of the family Tortricidae. The species was first described by Nietner in 1861. It is widely distributed in the Oriental region. The wingspan is 16–20 mm for males and about 23 mm for females. Adults are on wing between December and April in Sri Lanka. There are two generations per year in China with adults appearing in late May.
The larvae feed on Acacia auriculiformis, Arachis hypogaea, Bauhinia, Cajanus indicus, Calophyllum inophyllum, Camellia sinensis, Cinnamomum, Citrus, Coffea, Crotalaria, Derris, Eucalyptus alba, Eugenia polyantha, Glochidion, Gossypium, Linum, Melochia indica, Nephelium, Pluchea indica and Pyrus.
The tea tortrix has a life cycle which takes about 35 to 49 days to complete. Immediately after copulation, adult females lay 100 to 150 clusters of egg on the surface of the leaves of host plant. Eggs are scaly and minute with overlapping appearance. After 6 to 8 days of laying, larvae hatch from the eggs. Larvae complete five instars and become fully grown after 3 to 4 weeks. Fully grown caterpillar is about 22 mm in length. Pupation occurs in the folds... Wikipedia →

Rare
Under 5% of wildlife watchers report a Homona coffearia sighting in Hong Kong on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 778th 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 and June
In those months about 10% of wildlife watchers report a Homona coffearia in Hong Kong on a given day, against under 5% in May and July–March, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
2nd of 2
Of the 2 cities where we can rate Homona coffearia sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Kochi (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Homona coffearia is recorded against all the insects logged in Hong Kong (9 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.
