Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat and food source for the maker of the gall. The interior of a gall can contain edible nutritious starch and other tissues.
Often multiple wasps in different life stages occupy the same gall. The induced galls help establish complex insect communities, promoting the diversification in niche differentiation. Furthermore, the adaptive value of these galls could be attributed their ecological benefits such as nutrition, provision of microenvironment, and enemy avoidance.
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.

In the winter time galls of D. mayri are often opened by predators just as are the galls of D. rosae.These predators may be birds as in the case of other Cynipidae galls: for D. rosae the lesser spotted woodpecker (Picoides minor), [2] for Andricus spp. and Neuroterus spp. the great tit (Parus major).
Rhopalomyia solidaginis, the goldenrod bunch gall, is a species of gall midges, insects in the family Cecidomyiidae. The galls of this species have the following host species of goldenrods: Solidago altissima, Solidago canadensis, and Solidago rugosa. They have been found across eastern North America.
Gall's interior Witch Hazel Cone Galls. H. hamamelidis have three generations per year, each with a different part in the life cycle. At the start of spring, females or stem mothers crawl to witch-hazel leaf buds. As the leaf grows, the aphid injects it with a substance, possibly an enzyme or hormone, that
Some of these galls can be found in clusters near the shoot tip or in adjacent lateral buds. The spongy mass at the base of the gall gradually grows to a final size of 6 cm in diameter. The leaves encircling the mass are wider than the typical leaves of the plant, but they start to become loose in the second week of June.
