Tortoise beetle

Description:

The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. It includes both the former subfamily "Hispinae" (leaf-mining beetles), as well as the former more narrowly defined subfamily Cassidinae (familiar as tortoise beetles)

Notes:

The "cassidoids" have a rounded outline with the edges of the pronotum and elytra spreading out to cover the legs and head. They are often colourful and metallic, with the ability to change the colour (and lost in specimens) which is present in the living tissue below the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi.
