sunn pest, sunn bug, tortoise shieldbug
Eurygaster is a genus of shield bugs in the family Scutelleridae, distributed across Eurasia with some species in North America. The genus includes several economically significant agricultural pests, particularly E. integriceps and E. testudinaria, known as sunn pests that damage cereal crops. Species identification within the genus is challenging due to morphological similarities among closely related taxa. The genus comprises at least 17 extant species plus one fossil species, with six species recorded from Russia.
