Nematus erythrogaster
Nematus cf. erythrogaster is a tentative identification for a sawfly in the genus Nematus, distinguished by its reddish-orange abdominal coloration. The 'cf.' designation indicates morphological similarity to N. erythrogaster without confirmed species-level identification. Sawflies in this genus are herbivorous and often associated with willow (Salix) or poplar (Populus) host plants. The genus Nematus is widespread in the Holarctic region, with numerous species exhibiting similar color patterns that complicate field identification.
