The meristems, where plant cell division occurs, are the usual sites of galls, though insect galls can be found on other parts of the plant, such as the leaves, stalks, branches, buds, roots, and even flowers and fruits. Gall-inducing insects are usually species-specific and sometimes tissue-specific on the plants they gall.
Galls are growth deformities induced in certain plants by various insects which are mostly species-specific. Galls induced by insects can be viewed as an extended phenotype of the inducing insect, and gall-inducing insects specialize on their host plants, often to a greater extent than insects that feed on the same plant without creating galls.

The induced galls are shared with a community of insects including transient occupants, opportunistic foragers, parasitoids, inquilines, and parasitoids of inquilines. [2] These galls are divided into microscale niches allowing for the coexistence of ecologically similar species that exploit similar feeding strategies.
The host plant reacts by producing extra cells and the affected areas becomes swollen and rolls downwards and encloses the wax covered nymphs. Each gall may contain two or three generations and by the end of summer contain all stages of the insect. [1] The galls are pale-coloured with violet or red markings. [2]
Rhopalomyia solidaginis, the goldenrod bunch gall, is a species of gall midges, insects in the family Cecidomyiidae.
