Identification


ID/Diagnostic: Morphological

Morphological. Eurygaster nymphs lack distinguishing morphological characteristics and must be reared to adult to identify to species. Adults can be distinguished from other congeners based on morphological differences described in Ali and Khidhir (2016) including body size, the groove pattern on the clypeus, and the curve of the prothorax. The male genitalia is also a key character. See CPHST Pest datasheet for reference.
Mistaken Identities:
Eurygaster integriceps is difficult to distinguish from two congeners, E. maura and E. austriaca, without dissection. Neither species is known to occur in the United States. Images and diagnostic characters for E. maura and E. austriaca are available on the Pest and Disease Image Library (PaDIL) website (http://www.padil.gov.au/). There are five Eurygaster species present in North America: E. amerinda, E. alternata, E. minidoka, E. paderewskii, and E. shoshone. None of these species are pests of wheat.
