Carmenta mimosa is a moth of the Sesiidae family. It is native to Central America (Mexico, Honduras and Nicaragua), but has been introduced to the Northern Territory of Australia in 1989. Adults look like wasps, but have a wider connection between the thorax and abdomen. They have transparent wings with broad black margins. Their body is black, with a pair of white stripes on the thorax and three transverse white bands on the abdomen. The larvae feed on Mimosa pigra. They bore into the stems of their host plant, weakening the stem, which can cause it to break off and die.
