Cleobora mellyi (Peltoschema model)

This attractive beetle is one of the largest species of coccinellidae. They have clubbed antennae, non striate elytra which have explanate lateral margins, which easily distinguishes them from their mimics. The ladybird beetle is the model for several mimetic beetles which trade on the benefit of predators learning that ladybird beetles taste very bad. (I did not test this theory for myself.)
