Chelidonium cinctum
In 3 days ~10% in a week ~20%
Chelidonium cinctum is a species of long-horn beetle found in southern India. The larvae bore into the branches of citrus trees, sometimes causing damage in cultivated citrus crops. The adult beetles are a bit more than an inch long and are dark metallic blue with a transverse yellow to orange band midway on the elytra. The band is transverse in the inner half of the elytra and extends posteriorly on the outer edge. The adults emerge in May and June after the rains and eggs are laid in the leaf axils of citrus trees. The larvae hatch and bore into the shoots, boring upwards and then girdling the tip of the branch which withers and turns black. It then bores inwards and pupates, emerging in a year. The populations can cause damage in citrus cultivation where they are managed by physical removal of the adults and by cutting of the branches showing girdling damage. Wikipedia →

Rare
Under 5% of wildlife watchers report a Chelidonium cinctum sighting in Bengaluru on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 395th most-seen of the 477 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.
May and June
In those months about 10% of wildlife watchers report a Chelidonium cinctum in Bengaluru on a given day, against under 5% in July to April, the lowest months.
Only Bengaluru, in our data
Bengaluru is the only city on Wallace's Line with enough records to rate Chelidonium cinctum sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Chelidonium cinctum that you can see in Bengaluru (family Cerambycidae, Longhorn Beetles) are Lebbek Borer (about 10%), Clytocera chionospila (about 10%) and Albizia Long-Horned Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chelidonium cinctum is recorded against all the insects logged in Bengaluru (6 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.
