Coccinella transversalis, commonly known as the transverse ladybird or transverse lady beetle, is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. It is not to be confused with Coccinella transversoguttata, a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together.
The transverse ladybird was first described by Danish zoologist Johan Christian Fabricius in 1781 as Coccinella transversalis and still bears its original name. Fabricius' description predated Carl Peter Thunberg's naming of this species as C. repanda by several months.
Measuring 3.8 to 6.7 millimetres (0.15 to 0.26 in) long and 3.3 to 5.45 millimetres (0.130 to 0.215 in) wide, the transverse ladybird shows little variation across its wide range. It has a black head with predominantly bright red or orange elytra boldly marked with a black band down the midline and two lateral three-lobed markings.

With luck
About 10% of wildlife watchers report a Small Transverse Ladybird Beetle sighting in Kolkata on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 77th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Small Transverse Ladybird Beetle is recorded against all the insects logged in Kolkata (25 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.
