Common wireweed

''Sida acuta'', the common wireweed, is a species of flowering plant in the mallow family, Malvaceae. It is believed to have originated in Central America, but today has a pantropical distribution and is considered a weed in some areas.

In northern Australia, ''Sida acuta'' is considered an invasive species, and the beetle ''Calligrapha pantherina'' has been introduced as a biological control agent in an attempt to control the plant.
