Black beetles
Next Image Black beetles are mainly pests of pasture, but they also attack crops such as maize, sweet corn, potatoes, strawberries and kūmara (sweet potato). Adult beetles usually emerge in February, and after feeding for a few months spend winter in the soil. They resurface and lay their eggs about late spring. The larvae look like grass-grub larvae but are larger, and also eat grass roots. Pasture roots die off and the turf can be rolled back like a carpet. Black beetles prefer living in free-draining, sandy soils.

Comments
Judy Astleford01 March 2011 The black beetle that eats our strawberries seems to live in the soil and comes up underneath the strawberry fruit and burrows into it and often hollows it right out or leaves one or more holes in the fruit. It is very quick to burrow down into the soil and disappear if it is exposed. I put some in a zip lock plastic bag and they very quickly made a hole in it and escaped! I put some in my pants pocket and could soon feel them eating there way through and had to remove them. How does one get rid of these pests?Tag » What Does Black Beetles Eat
