Pupae can be classified into three types&colon; obtect, exarate, and coarctate. There are three types of pupae&colon; obtect, exarate or coarctate. The pupae are whitish, exarate (with free appendages), and similar in size to the adult. The pupae of Diptera can be obtect, exarate or coarctate. Exarate pupae have their legs and other appendages free and extended. The pupae are cream-coloured and exarate (with free appendages). Pupae are exarate, allowing movement of the exposed abdomen. The pupae have free appendages rather than being secured within a cocoon (they are exarate).
