- D. u. howardi – spotted cucumber beetle (southern corn rootworm)
- D. u. tenella – western cucumber beetle
- D. u. undecimpunctata – western spotted cucumber beetle
In the adult form, it eats and damages leaves of many crops, including cucumbers, soybeans, cotton, beans, and many others. In the larval form, which is known as the southern corn rootworm, it tunnels through the roots of young plants, stunting or killing them. These native pests have a wide range of host plants, but will readily infest a field of crop plants, most notoriously corn.
