1- Parallelodiplosis subtruncata(Dogwood Eyespot Gall Midge)
Parallelodiplosis is a of gall midges in the Cecidomyiidae, described by Rübsaamen in 1910. The genus contains at least 20 described . Like other cecidomyiids, these are small, delicate flies whose larvae induce gall formation on plants. The genus is distributed across northern Europe and North America.

Identification
Identification to requires examination of morphological features including structure, wing venation, and genitalia. As with most cecidomyiid genera, definitive identification typically requires microscopic examination and comparison with . The genus name refers to the parallel arrangement of certain morphological structures, though specific diagnostic characters distinguishing Parallelodiplosis from related gall midge genera require taxonomic knowledge.

Distribution
Recorded from Denmark (DK), Norway (NO), Sweden (SE), and the United States (specifically Vermont). The has a transatlantic distribution spanning northern Europe and eastern North America.
Life Cycle
As with all Cecidomyiidae, development includes , larval, pupal, and stages. Larvae are gall-formers on plant , though specific host plants for most Parallelodiplosis remain undocumented.
Ecological Role
Larvae function as gall inducers, causing abnormal plant growth that provides protected feeding sites. This interaction represents a specialized plant-herbivore relationship characteristic of the Cecidomyiidae.
