Dorytomus taeniatus is a species of weevil native to Europe. [2] [3] It was first described by Johann Christian Fabricius in 1781. The larvae cause a small growth (known as a gall) on the catkins of willows (Salix species).
Eggs are laid during the autumn in the axils of catkin buds and hatch the following spring. [4] The larvae cause an inconspicuous distortion of, usually, female catkins, thickening the rachis. [5] Catkins drop earlier than uninfected catkins and the larvae pupate in the soil. [6] Close examination of the gall is necessary as Redfern et al. (2011) note that sometimes, thickening of the rachis can be wound tissue rather than a gall and according to Plant Parasites of Europe identification is only possible by examining the weevils. [5] [6]
The gall has been recorded from white willow (S. alba), eared willow (S. aurita'), goat willow (S. caprea), grey willow (S. cinerea) and purple willow (S.purpurea). [6]
Adults are 4–5 millimetres (0.16–0.20 in) long and brownish-black to black. They can be found from May onwards, browsing on the leaves, removing patches of tissue and exposing the network of fine veins. [4]
Found in western and central Europe including Great Britain (common) and Scandinavia. [7]
Aceria fraxinivora, also known as the cauliflower gall mite and the ash key gall, causes the growths, known as galls, found on the hanging seeds or "keys" of the ash (Fraxinus species.
Andricus aries is a species of gall-forming wasps, in the genus Andricus. The species was named by the French entomologist Joseph-Étienne Giraud, in 1859. It is commonly found in eastern Europe and during the 21st century has spread to western Europe.
Rabdophaga heterobia is a species of gall midges which has two generations a year and forms galls on almond willow. It was first described by Hermann Loew in 1850.
Euura amerinae is a species of sawfly belonging to the family Tenthredinidae. The larvae form galls on bay willow. It was first described by Carl Linnaeus in 1758.
Euura weiffenbachiella is a species of sawfly belonging to the family Tenthredinidae. The larvae forms galls on creeping willows. E. weiffenbachiella is one of a number of closely related species which is known as the Euura atra subgroup.
Euura salicispurpureae is a species of sawfly belonging to the family Tenthredinidae. It was first described by Jens-Peter Kopelke in 2014. The larvae feed within galls on willows. E. salicispurpureae is one of a number of closely related species known as the Euura atra subgroup.
Rabdophaga justini is a gall midge. It was first described by Horace Francis Barnes in 1935. The larvae tunnel in the shoots of purple willow.
Aculus craspedobius is a species of mite which causes galls on the leaves of willows. It was first described by Alfred Nalepa in 1925.
Rabdophaga marginemtorquens is a gall midge which forms galls on willows. It was first described by Johann Jacob Bremi-Wolf in 1847.
Rabdophaga clausilia is a gall midge which, depending on the source, forms galls on the leaves of willows, or is an inquiline living in the galls of a Rabdophaga species, or a predator. It was first described by Johann Jacob Bremi-Wolf in 1847.
Euura oblita is a species of sawfly belonging to the family Tenthredinidae. The larvae feed on the leaves of willows and was first described by Jean Guillaume Audinet-Serville in 1823.
Euura destricta is a species of sawfly belonging to the family Tenthredinidae. The larvae feed on the leaves of willow.
Euura dolichura is a species of sawfly belonging to the family Tenthredinidae. The larvae feed within galls on the leaves of willow. Some of the Euura species of sawfly are closely related and placed in groups of similar species. E. dolichura is a member of the Euura dolichura species group.
Euura proxima is a species of sawfly belonging to the family Tenthredinidae. The larvae feed on the leaves of willows and was first described by Jean Guillaume Audinet-Serville in 1823.
Euura vesicator is a species of sawfly belonging to the family Tenthredinidae. The larvae feed internally in a gall on the leaves of purple willow and its hybrids. It was first described by Johann Jacob Bremi-Wolf in 1849.
Euura herbaceae is a species of sawfly belonging to the family Tenthredinidae. The larvae feed internally in a gall formed on the leaves of dwarf willow and polar willow. Galls of E. aquilonis are similar and the larvae need to be examined to tell them apart.
