New Zealand biosecurity officials have identified the presence of a Hadda beetle in Auckland, the country's Ministry of Agriculture and Forestry (MAF) said in a press release.

The beetle was discovered and reported by an entomologist who has a close association with MAF Biosecurity New Zealand.

Response manager David Yard said the beetle causes distinctive damage to foliage.

"The leaf surface is scraped away leaving irregular windows or parallel strips. This feeding damage gives leaves a distinctive ‘lace-like' appearance which is quite visible. Both adults and larvae feed on the host plants," he said.

"The species are found throughout Asia and the Pacific region and are foliage feeders that feed on solanaceous crops including potatoes, tomatoes, and aubergines."

Contractors have carried out a controlled spraying programme near where the beetle was found with a commonly used insecticide.

"A surveillance programme is also planned to determine the extent of the infestation. While there are no human health concerns, the public are encouraged not to enter these areas until the signage and cordons are removed," Mr Yard said.

Hadda beetle larvae are about 7mm long, pale yellow in colour with black spiny hairs. Adults are 7-10 mm in size and yellow/orange coloured with around 26 black spots on their backs.
