Caliroa nyssae
tupelo sawfly, black gum sawfly
Caliroa nyssae is a sawfly species in the family Tenthredinidae that feeds on Nyssa sylvatica (black tupelo or black gum). The larvae skeletonize leaves, leaving a characteristic lace-like pattern of veins. This species is part of a genus of oak-skeletonizing sawflies, though C. nyssae has specialized on tupelo rather than oak. Adults are small, dark-colored sawflies with the typical broad waist characteristic of suborder Symphyta, distinguishing them from the narrow-waisted wasps in suborder Apocrita.
