Gall Wasps and Allies
Cynipoidea is a superfamily of small wasps comprising approximately 3,000 described species across seven extant families, with many undescribed species estimated. The group exhibits diverse life histories: while the family Cynipidae (gall wasps) are phytophagous and induce plant galls, the majority of species are parasitoids or hyperparasitoids of other insects. The superfamily is taxonomically challenging, with family-level identification historically difficult until the publication of a comprehensive illustrated key in 2020.

ash bullet gall midge
Dasineura pellex, commonly known as the ash bullet gall midge, is a species of gall midge in the family Cecidomyiidae. The species induces distinctive bullet-shaped galls on ash trees (Fraxinus spp.). Like other members of the genus Dasineura, it is a specialist herbivore with a close association to its host plant. The species has been documented across parts of North America, with records from the northeastern United States including Vermont.
Dimorphopteryx abnormis
Dimorphopteryx abnormis is a species of sawfly in the family Tenthredinidae, subfamily Allantinae. The genus Dimorphopteryx is characterized by unusual wing dimorphism, with both fully winged and short-winged forms occurring within species. This species was described by Rohwer in 1911 and is known from multiple Canadian provinces. Like other tenthredinid sawflies, it is likely herbivorous with larvae feeding on plant foliage, though specific host plant associations remain poorly documented. The genus is taxonomically notable for its distinctive wing polymorphism, which is reflected in its name (Greek: dimorphos = two forms, pteryx = wing).
