Critter of the Week The Wellington south coast speargrass weevil

From Afternoons with Jesse Mulligan, 3:28 pm on 8 June 2018

These flightless, large insects are at risk largely from lack of host plants (speargrass).  They are 2 cm-long and vulnerable to extinction because they are monophagic - which means they only eat one plant species. But the main issue is that they are flightless and slow-moving, making them highly vulnerable to predation by rats and mice
