Hycleus is a genus of blister beetle belonging to the Meloidae family found in Africa and Asia.

[1] 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.
