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 ...
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.
The main purpose of this page is to list the current standard time offsets of different countries, territories and regions. Information on daylight saving time or historical changes in offsets can be found in the individual offset articles (e.g. UTC+01:00) or the country-specific time articles (e.g. Time in Russia).
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.
As the larvae mature, they become c-shaped grubs, which consume progressively coarser roots and may do economic damage to pasture and turf at this time. Larvae hibernate in small cells in the soil, emerging in the spring when soil temperatures rise again. [13] Within 4–6 weeks of breaking hibernation, the larvae will pupate.
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.
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 ]
