Description

Polychalca punctatissima can reach a length of about 13–17 millimetres (0.51–0.67 in). These beetles feed on Black Sage ( Cordia cylindrostachya , Boraginaceae).

Distribution

This species can be found in Brazil and Argentina.

Use in jewelry

The new wave of Victorian Egyptomania following the opening of the Suez Canal in 1869 increased the demand for Egyptian jewelry, especially scarabs. This, combined with an increased interest in the natural world, lead to the import of Polychalca punctatissima carapaces from South America for use in jewelry as "scarabs". [1] [2]
