Parthenium beetle (Zygogramma bicolorata)

The Parthenium beetle (Zygogramma bicolorata) is so called as its larvae feeds on the leaves of the highly invasive Parthenium weed.

It is of Mexican origin, but was introduced into Bangalore in 1984 to control the Parthenium hysterophorus weeds. It is now a well established species in India.

Some variation in the pattern on the wing is common.
