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.

Diplolepis rosae is a gall wasp which causes a gall known as the rose bedeguar gall, bedeguar gall wasp, Robin's pincushion, mossy rose gall, or simply moss gall. [ 1 ] [ 2 ] The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose ( Rosa arvensis ) or dog rose ( Rosa canina ) shrubs.
The Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. [1] Larvae of the other ( basal ) cecidomyiid subfamilies feed on fungi; whereas this subfamily is best known for its members that induce galls on plants.
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls . Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long.
This bowing is temporary, only occurring during the egg laying period of species that use the plant as a host, such as goldenrod gall fly (Eurosta solidaginis) and the goldenrod bunch gall midge (Rhopalomyia solidaginis). [14] Insect species inject their eggs into goldenrod buds causing spherical swelling on the plant known as a gall. [15]
Oak galls have been used in the production of ink since at least the time of the Roman Empire. From the Middle Ages to the early twentieth century, iron gall ink was the main medium used for writing in the Western world. [2] Gall nuts are a source of tannin in the production of iron gall ink. Tannins belong to a group of molecules known as ...
