Botany Bay diamond weevil
Native to this country in the south-east, taking the title of 'first insect from Australia', after being collected by Sir Joseph Banks when Captain Cook’s expedition landed in Botany Bay in 1770, then recorded officially in 1775 by Danish entomologist Johan Fabricius.
It is a lovely looking insect whose colour is predominantly black with patches of metallic blue or green scales. Both immature and adult stages live on just 28 of our 1000 Acacia species. The larvae form tunnels in the trunk and roots of the plant.
N.B. not captive, seen making its way across a garden patio.
25 mm body length, perhaps female as they are the larger size.
''Chrysolopus spectabilis'' is a species of weevil found in south-eastern Australia. It is up to 25 mm long, with metallic green patterns on a black background. It is a specialist, only known from 28 species of ''Acacia''.
