#3788 - Pantomorus cervinus - Fuller's Rose Weevil
Terrible photos of a weevil who seems to have lost a jaw and both antennae at some point.
Variously placed in Naupactus, Asynonychus, and Aramigus over the years. My sources disagree on whether the currently accepted binomial is Naupactus cervinus or Pantomorus cervinus. The epithet means 'fawn-coloured'.
The common name refers to American horticulturist A.S. Fuller, who first identified the insect as a significant pest of rose bushes in the late 19th century.
Original found in Central and South America, now introduced to many other parts of the world. Given they're wingless that must have involved a lot of walking. They're also parthenogenic - males have never been found.
Agricultural pests whose larvae feed in the roots of of Roses, Camellias, Geraniums, Primroses, Citrus trees, Avocados, Apples, peaches, plums, apricots and many other plants. The garden at Oamaru had at least five of those so it must have been a smorgasbord for the weevil.
