Identity

Charidotella sexpunctata is a leaf beetle in Chrysomelidae, within the tortoise-beetle subfamily Cassidinae. [1][2]

Appearance

The adult is nearly circular and flattened, with the pronotum extending over the head and translucent margins around the wing covers. Living individuals may appear metallic gold or orange and can change to red or brown when disturbed. [1][2]

Range and habitat

The species is distributed across the Americas and occurs on its Convolvulaceae host plants, including in Missouri. [2][1]

Life cycle

Females place eggs on the undersides of host leaves and provide no subsequent parental care. [2]

Food and hosts

Adults and larvae eat the leaves of morning-glory relatives, including bindweed and sweet potato. [1][2]

Behaviour

Larvae often feed together in groups on host foliage. [2]

Remarkable detail

A fork at the larva’s rear supports accumulated faeces and shed skins. The larva holds this material above its body as a defensive shield. [2]

Names and history

The epithet sexpunctata means six-spotted. Spots can become more conspicuous when the adult loses its golden sheen. [2]

Specimen views

Drying changes the adult’s visible appearance: a preserved beetle may be reddish or brown rather than brilliant metallic gold. [2]

Display and care

Keep the enclosure closed and display it in indirect light, away from heat and damp conditions. Handle the frame by its edges and clean only its exterior according to the maker’s instructions.
