What insect is known as the Southern green stink bug?

The Southern green stink bug is correctly identified as Nezara viridula. This insect is known for its distinctive green color and is commonly found in agricultural fields, where it can cause damage to various crops by feeding on their sap. Recognizing this specific insect is crucial for pest management practices, as it has significant economic implications for farmers due to its role as a pest in many agricultural settings.

Lissohoptrus oryzophilus, for instance, is a rice water weevil, while Triops longicaudatus is a type of tadpole shrimp.

Understanding these distinctions in taxonomy and behavior is essential for proper pest identification and management in agricultural practices.
