What specific food source do the C-shaped white grubs, referred to as curl grubs, consume beneath the lawn or turf?
Answer
Grass roots
The larval stage of the Christmas beetle, commonly known as curl grubs, exhibits a highly specialized diet consisting entirely of the subterranean parts of plants, specifically grass roots. Because these larvae reside hidden beneath lawns and turf, their feeding activity can go unnoticed until significant biomass has been consumed. The consumption of these foundational nutrient supplies leads directly to noticeable damage, causing large patches of grass to die due to the severing of their connection to the soil and water supply. This contrasts sharply with the diet of the adult beetles, whose feeding habits focus exclusively on foliage above ground.
