Arge macleayi

Arge macleayi is a species of sawfly in the family Argidae, a group of herbivorous hymenopterans often mistaken for wasps or flies due to their broad waist and two pairs of membranous wings. The genus Arge is among the most species-rich in Argidae, with adults typically recognized by their distinctive antennae and often striking coloration. Records indicate this species occurs in multiple Canadian provinces, suggesting a northern temperate distribution.
