What key element attracts the egg-laying female beetle, separate from the adult's need for foliage?
Answer
Locations offering the best chance for offspring survival
While the mature, flying beetle is strongly drawn to eucalypt leaves for direct sustenance, the behavior of the egg-laying female is driven by the necessities of her offspring. Her primary directive is selecting a site that guarantees the survival of the next generation immediately after hatching. This survival is secured by depositing eggs into the soil directly beneath the preferred adult host plants, ensuring that when the larvae emerge, they are positioned perfectly to begin feeding on the nearby grass and turf roots, linking reproductive strategy to larval habitat.
