Henosepilachna vigintioctopunctata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird or the Hadda beetle. It feeds on the foliage of potatoes and other solanaceous crops. It was previously called Epilachna vigintioctopunctata and is a cryptic species complex. It is very often confused with a closely related species, Henosepilachna vigintioctomaculata, which occurs in Russia, China, Japan, and Korea, and is given the same "common name".
Temperature and humidity strongly influence the seasonal abundance of this species; the population increases with increased minimum temperature, and higher relative humidity. However, this species has two natural enemies, Tetrastichus sp. and Pediobius foveolatus, that suppress the beetle population by parasitizing their larval and pupal stages.
This species is native to southeastern Asia, primarily India, but has been accidentally introduced to other parts of the world, including Australia and New Zealand. It has also been recorded from Brazil and Argentina, beginning in 1996.

With luck
About 10% of wildlife watchers report a Hadda Beetle sighting in Royal National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 175 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January to March
In those months about 10% of wildlife watchers report a Hadda Beetle in Royal National Park on a given day, against under 5% in April to December, the lowest months. Those are among Royal National Park's wettest months, with about 130 mm of rain a month against 50 mm in August.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Hadda Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 parks where we can rate Hadda Beetle sightings, Royal National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Lamington National Park (Australia, about 10%) and Springbrook National Park (Australia, about 10%).
Same family: Coccinellidae
The closest relatives of the Hadda Beetle that you can see in Royal National Park (family Coccinellidae, Lady Beetles) are Large Spotted Ladybird (about 20%), Fungus-Eating Ladybird (about 10%) and Small Transverse Ladybird Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hadda Beetle is recorded against all the insects logged in Royal National Park (5 verified sightings from 2019 to 2026), 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.
