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 Brisbane on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 760th most-seen of the 1083 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.
February
In that month about 10% of wildlife watchers report a Cabbage Cluster Caterpillar in Brisbane on a given day, against under 5% in March to January, the lowest months. That is one of Brisbane's wettest months, with about 160 mm of rain against 40 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cabbage Cluster Caterpillar sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 4
Of the 4 cities where we can rate Cabbage Cluster Caterpillar sightings, Brisbane ranks 4th at under 5%. The best odds are in Harare (Zimbabwe, about 10%), Tuen Mun (China, under 5%) and Durban (South Africa, under 5%).
Same family: Crambidae
The closest relatives of the Cabbage Cluster Caterpillar that you can see in Brisbane (family Crambidae, Crambid Snout Moths) are Grass Webworm Moth (about 20%), Hawaiian Beet Webworm Moth (about 10%) and Culladia cuneiferellus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cabbage Cluster Caterpillar is recorded against all the insects logged in Brisbane (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.
