Neolasioptera nodulosa
(Beutenmüller, 1907)
nodular stem gall midge
Neolasioptera nodulosa is a gall midge in the Cecidomyiidae, commonly known as the nodular stem gall midge. The induces characteristic nodular galls on plant stems. It was first described by Beutenmüller in 1907. As a member of the gall midge family, it is part of a diverse group of flies whose larvae develop within plant tissue, causing distinctive growth deformities.

Identification
Identified by the presence of characteristic nodular stem galls on plants; require examination of antennal segmentation, wing venation, and genitalia to distinguish from other Neolasioptera . The specific gall —nodular swellings on stems—serves as the primary field indicator.

Appearance
are small, delicate flies typical of the Cecidomyiidae, with long, slender legs and bearing bead-like segments. The is distinguished by the nodular stem galls induced by its larvae—swollen, irregular growths on plant stems. Specific adult morphological features distinguishing N. nodulosa from are not documented in available sources.
Habitat
Associated with plants bearing stem galls; specific preferences beyond host plant requirements are undocumented. Gall midges generally occur in areas where their host plants grow, including meadows, forests, and disturbed vegetation.
Distribution
Documented from Vermont, United States, based on GBIF distribution records. Broader North American range likely but insufficiently documented in available sources.
Host Associations
