Adults:
The adult beetles measure about 1/5 inch (5 mm) long by 1/10 inch
(2.5 mm) wide. The upper body surface is yellow with black spots.

Eggs:
Eggs are orange-yellow in color and are laid around the base of
the host plants, often below the soil surface or in cracks in the
ground. The eggs hatch in about one week. |

|
Larvae:
The white larvae that hatch from the eggs feed for a period of 2-6
weeks, depending on temperature, on the roots and underground portion
of the plant where they may damage the root system. When full grown,
the larvae are about 1/3 inches ( 8 mm) long. |
|
Pupae:
The larvae transform to pupae in the soil near the base of the plants
on which they have been feeding. The white pupae transform into
adult beetles in about one week. |
