Hycleus biundulatus
In 3 days ~20% in a week ~40%
Hycleus biundulatus is a species of blister beetle found in India, Sri Lanka, China, Java, and Pakistan. Adults feed mainly on flowers from a wide range of plant families. The first larval instar is an active triungulin form that is a predator of soft insects such as aphids. While the young are often beneficial to crops by suppressing other plant feeders, the adults can be a problem when present in large numbers. Flower feeding leads to lower yield and this can be a problem in some leguminous crops. They are however easily controlled by manual collection.

GBIF citizen-science records
It is estimated from how often the Hycleus biundulatus is recorded against all the insects logged in Chennai (12 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.
