The grub population consists mainly of first instars in early- to mid-August, second instars by early September, and third instars by mid-September to early October. In frost zones, the grubs feed until November, then move deeper into the soil. In frost-free areas, the larva will feed all winter. Vigorous feeding occurs from March through May.
Gravity anomaly maps of the British Isles are interpreted as indicating the presence of granite plutons in the following areas. The list is not exhaustive: Galloway, UK; Cheviot Hills, UK; Mountains of Mourne, UK; Connemara, Ireland; County Donegal, Ireland; South West England (Cornubian batholith and Haig Fras granite), UK; Askrigg Block ...
The larvae, known as "chafer grubs" or "white grubs", hatch four to six weeks after being laid as eggs. They feed on plant roots, for instance potato roots. The grubs develop in the earth for three to four years, in colder climates even five years, and grow continually to a size of about 4–5 cm, before they pupate in early autumn and develop ...
The mountains of northwest Ireland were formed during the collision, as was the granite that is found in locations in Donegal and Wicklow. The Irish landmass was now above sea level and lying near the equator , and fossil traces of land-based life forms survive from this period.
"Drift" geology is often more important than "solid" geology when considering building works, drainage, siting water boreholes, sand and gravel resources and soil fertility. Although "drift" strictly refers to glacial and fluvio-glacial deposits, the term on geological maps has traditionally included other materials including alluvium, river ...
"Drift" geology is often more important than "solid" geology when considering building works, drainage, siting water boreholes, soil fertility, and many other issues. Glaciation and the resulting glacial and fluvio-glacial deposition has had a major impact on the landscape of England covering many areas with a veneer of glacial till in the ...

However, white grubs (reaching 40–45 mm long when full grown) live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens, and golf courses. An obvious indication of infestation is the presence of birds, such as crows, peeling back the grass to get to the grubs.
