The feeding behaviour of the hedgehog (Erinaceus europaeus L.) in pasture land in New Zealand.
A population of hedgehogs (Erinaceus europaeus L.) in pasture land in Canterbury was found to vary between less than four and eight per hectare. Feeding habits were studied through stomach contents and analysis of faeces. Grass grub beetles (Costelytra zealandica) and porina moths (Wiseana cervinta), both important pasture pests, were relatively important food items. Estimates of the number of grass grubs eaten in relation to their density and that of hedgehogs in pastures show that hedgehogs are potentially capable of consuming 10-40 percent of adult populations.
