Crocidolomia pavonana is a moth of the family Crambidae. Its caterpillar is a crop pest and is known as the croci or the cabbage cluster caterpillar. This moth is found in Africa and Asia, its range extending from South Africa through India to the Pacific Ocean, including Australia. The wingspan is about 25 mm (1 in). The larvae feed on Brassicaceae species and are considered an agricultural pest on cabbages. The species was first described by Johan Christian Fabricius in 1794.
The adult male is between 11 and 14 mm (0.43 and 0.55 in) long with a wingspan of 20 to 25 mm (0.8 to 1.0 in), and the female is slightly smaller. Both are rather variable in colouring but have brownish markings on a cream background. The male can be distinguished by the tufts of dark-coloured hairs at the front of the forewings.
The eggs are pale green and up to three hundred are laid in an overlapping pile that may be 5 mm (0.2 in) in diameter. The larvae are grey with dark heads when they hatch and later become green with dark heads and five fine pale yellow longitudinal stripes. The pupa is cylindrical, olive green to light brown, becoming darker shortly before emergence. It is surrounded... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cabbage Cluster Caterpillar sighting in Tuen Mun on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 492nd most-seen of the 557 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and April
In those months about 10% of wildlife watchers report a Cabbage Cluster Caterpillar in Tuen Mun on a given day, against under 5% in March and May–January, the lowest months. Those are among Tuen Mun's driest months, with about 70 mm of rain a month against 290 mm in June.

GBIF citizen-science records
It is estimated from how often the Cabbage Cluster Caterpillar is recorded against all the insects logged in Tuen Mun (5 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.
