Gall-inducing insect Gall-inducing insect A gall-inducing insect is any insect that can cause the growth of galls within plants. The term gall fly is also used to cover these species, although most are not true flies. There are several groups of insects that meet this description. They include the gall wasps, scales, gall midges, aphids, psyllids and certain species of leafminer flies. Galls are growth deformities induced in certain plants by various insects which are mostly species-specific. The gall's form or type depends on what organism is attacking the plant and where the plant is being attacked. Based on the form, there
Green-head ant 1863 he moved the ant from "Rhytidoponera" to "Ectatomma". In 1897 Italian entomologist Carlo Emery named the ant "Rhytidoponera metallica" and in 1911 designated it as the type species of "Chalcoponera", a subgenus of "Rhytidoponera"; the ant was, however, mistakenly identified as the type species of "Rhytidoponera" by some scientists. The taxonomy of the green-head ant and other species related to it (forming the "R.metallica" species group) were a source of confusion due to the high geographic variations in the green-head ant and similar-looking species having been treated as forms (occurrence of multiple morphs). These forms have been described under
