In 3 days ~10% in a week ~20%
Tetragonus catamitus, the common butterfly moth, or Philippine callidulid moth, is a moth of the family Callidulidae. It was first described by Carl Geyer in 1832. Noted from Taiwan, north-eastern India, south-west India, the Andaman and Nicobar Islands, Sri Lanka, the Tenasserim Hills of Myanmar and from Java. They are day-flying moths that can be easily mistaken for a butterfly due to the position in which they hold their wings.
The head, thorax and abdomen are dark yellowish and reddish brown. The wings are yellowish and reddish brown. The hindwings are more uniform reddish brown. On the underside, there are dark striations and both the forewing and hindwing have three grey spots in the discal cell. There are four pale rufous bands along the medial, postmedial, submarginal region.
The species was named Tetragonus catamitus by Carl Geyer in 1832 based on a specimen from Java and later described under the name of Cleosiris fasciata by Frederic Moore. The larvae were described later as being translucent green with a dark black semi-prognathous head and a prothorax with a well-developed prothoracic shield. Young instar larvae live in a rolled leaf, and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Butterfly Moth sighting in Singapore on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 451st most-seen of the 1045 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.
July and October
In those months about 10% of wildlife watchers report a Common Butterfly Moth in Singapore on a given day, against under 5% in August–September and November–June, the lowest months.
3rd of 3
Of the 3 cities where we can rate Common Butterfly Moth sightings, Singapore ranks 3rd at under 5%. The best odds are in Kochi (India, about 10%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Butterfly Moth is recorded against all the insects logged in Singapore (30 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.
