Batocera rufomaculata, also known as the mango stem borer or MSB, is a species of long-horn beetle in the family Cerambycidae. It was described by Charles De Geer in 1775. It is native to China, India, Laos, Malaysia, Myanmar, Pakistan, Sri Lanka, Thailand, and Philippines, and has been introduced to many other countries, including Israel, Jordan, Lebanon, Madagascar, Mauritius, Puerto Rico, Réunion, Syria, and the Virgin Islands.
Larvae bore into the trunks of Ficus carica, Carica papaya, Mangifera indica, and Shorea robusta and range of other plants. In fruit tree cultivation, such as that of mango, they can cause loss of yield and death of the trees. It can be parasitically infected by Avetianella batocerae. Wikipedia →

With luck
About 10% of wildlife watchers report a Mango Stem Borer sighting in Kolkata on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 136th most-seen of the 213 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.
April–May and July–October
In those months about 10% of wildlife watchers report a Mango Stem Borer in Kolkata on a given day, against under 5% in June and November–March, the lowest months. Those are among Kolkata's wettest months, with about 210 mm of rain a month against 10 mm in December.
3rd of 11
Of the 11 cities where we can rate Mango Stem Borer sightings, Kolkata ranks 3rd at about 10%. The best odds are in Jamshedpur (India, about 30%) and Visakhapatnam (India, about 20%).
Same family: Cerambycidae
The closest relatives of the Mango Stem Borer that you can see in Kolkata (family Cerambycidae, Longhorn Beetles) are Bamboo Tiger Longhorn (about 10%) and Lebbek Borer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mango Stem Borer is recorded against all the insects logged in Kolkata (10 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.
