Rhogogaster viridis is a species of common sawfly in the family Tenthredinidae.

These rather rare sawflies can be found mainly in grassy environment, gardens and parks rich in green leaves.

Like other species in its genus, this sawfly has a light green head and body.

[citation needed] They mainly feed on pollen and nectar, but, on sunny summer days, they hunt for insects and suck out their body fluids, feeding especially on Colorado Potato Beetle (Leptinotarsa decemlineata).

[3][obsolete source] The larvae are similar to caterpillars, but they have six true legs and several abdominal prolegs.
