Description

Parisopalpus nigronotatus is generally coloured brick-red, with dark spots found on the beetle's body and legs. The species is densely covered with pale hair. The beetle is typically between 8.7 and 12.2 mm in length.[2]

Parisopalpus nigronotatus can be told apart from other species of Parisopalpus by the presence of at least two dark spots on the beetle's body.[2]

Distribution

Parisopalpus nigronotatus is found in eastern Australia, south-eastern Australia and Tasmania.[3] It was introduced to New Zealand in 1931,[4] and is found in Nelson and the North Island.[2]

The species has been intercepted by biosecurity in Chile.[5]

Behaviour

The beetles lay their eggs in mangroves.[4] Grubs of the species are typically found in rotting wood, and as adults the beetles feed on nectar and pollen, and are attracted to light.[6]

The beetles secrete a toxic substance as a defense, which causes skin blisters in humans if touched.[4][6]
