Costelytra giveni is endemic to and found throughout New Zealand. There are, however, similar species found in other countries like Acrossidius tasmaniae, the Tasmanian grass grub found in Tasmania, Australia. Grass grubs prefer altitudes below 1200m, with favored soil types being free-draining loam soils, but they are also found in peaty or ...
Maladera formosae, commonly known as the Asiatic garden beetle and formerly known as Maladera castanea, is a species of beetle in the family Scarabaeidae.It is native to Japan, China, South Korea, North Korea, and Russia but was introduced to North America in the 1920s where it is considered a pest of turfs, gardens, and crop fields.
Female chafers lay 20-40 eggs over their lifespan. They are laid singly, 5–10 centimetres (2–4 in) deep in moist soil, and take 2 weeks to hatch. The grubs hatch by late July. 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 ...
Costelytra zealandica (commonly known as the grass grub) [1] is a species of scarab beetle found in forested areas of greater Wellington. [ 2 ] [ 3 ] It was originally described in 1846 by the British entomologist Adam White as Rhisotrogus zealandicus from a specimen obtained during the Ross expedition . [ 4 ]
Contrarily, grubs that develop within 3–4 years in the forest soil cause severe, long-term damage on young trees by feeding on roots. [3] In northeastern France, specifically in the Vosges Mountains , M. hippocastani populations have been at epidemic levels since 2007, and high larval densities have been recorded, which induces a high ...
Holotrichia is a genus of beetle in the family Scarabaeidae, which are well known as "chafer beetles" or "white-grubs" for their white larvae that are found under the soil where they feed on the roots of plants.

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 ...
