The Spotted Maize Beetle is indigenous to South America
where its distribution includes Argentina, Bolivia and Brazil. It is thought to
have been introduced into South Africa in about 1916.
Larvae. The larvae (termed grubs) live in the soil,
feeding on decayed vegetable matter. They are a pest in
maize fields because
they feed on newly planted maize seeds, causing damage both before and after
about maize pests...
Adults. The adults occur in large numbers in
January and February, feeding on pollen from a wide variety of plants. Even
though occurring in large numbers, they don't usually cause sufficient
damage to warrant attempting to control them with insecticides.
