Amaurochrous dubius nymph – formerly called black rice bug or turtle bug.

Amaurochrous dubius (Palisot)

This species is related to the rice stink bug as evidence by their odor when disturbed. These bugs are sometimes called turtle bugs. Neither the term black rice bug nor turtle bug is the correct common name for this insect. Both nymphs and adults cause damage by feeding with their piercing mouthparts. Feeding on the leaf sheath can cause dead or dying leaves, usually lower leaves, in otherwise healthy rice. The damaged leaves will often have a yellow, orange or red coloration.
