Gall-inducing insects are usually species-specific and sometimes tissue-specific on the plants they gall. Gall-inducing insects include gall wasps, gall midges, gall flies, leaf-miner flies, aphids, scale insects, psyllids, thrips, gall moths, and weevils. [36] Many gall insects remain to be described. Estimates range up to more than 210,000 ...
The gall itself is a typical oak apple gall in appearance, roughly spherical and varies from greenish to reddish or orange depending on host, age and environmental conditions. The galls range in size from a 2–14 cm across and often contain multiple larvae as well as parasites and other species that form a mutual relationship by feeding off ...
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. [2] The gall's form or type depends on what organism is attacking the plant and where the plant is being ...
Pemphigus spyrothecae, or the poplar spiral gall aphid, is a social insect which exhibits apparent altruistic behaviors. The aphids form galls and act as colony defenders, at times sacrificing their own lives to do so.
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.
The diameter of the gall at its base is 1.5–3 mm (0.06–0.12 in). [36] [31] They are narrow and conical, and sometimes have a slight curve at the tip. [16] The galls each contain a single chamber, [31] which is smooth inside. [24] Common names for the gall include the grape-leaf trumpet-gall, [35] the conical grape gall, [24] and the grape ...
