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.
Particularly well known species include Holotrichia serrata which is a serious problem in sugarcane cultivation and Holotrichia consanguinea which is a problem in groundnut cultivation. [2] Holotrichia parallela is known as the "dark/large black chafer" or "Asian cockchafer" and is a serious agricultural pest of sweet potato, peanut and soybean crops in China. [3]
Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 20 millimetres long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.
The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several subfamilies have been elevated to family rank, and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023).
The common cockchafer, colloquially called the Maybug, Maybeetle, or doodlebug, is a species of scarab beetle belonging to the genus Melolontha native to Europe. It is one of several closely related and morphologically similar species of Melolontha called cockchafers, alongside Melolontha hippocastani. The adults and larvae feed on plants, and are regarded as serious agricultural pests of crops such as grasses and fruit trees.
Melolontha hippocastani is a species of scarab beetle native to Eurasia, with its range spanning from Europe to China. It is one of several species in the genus Melolontha known as cockchafers, alongside the common cockchafer and Melolontha pectoralis. The adults are around 20–29 mm in length. It is distinguished from Melolontha melolontha by the shape of its pygidium, which is primarily black in colour. It primarily dwells in forests, and as such is commonly known as the forest cockchafer. Females lay their eggs in soil, and the larvae feed on decaying organic matter and later small plant roots, including the roots of young trees like pines and firs. The larvae usually develop between 3 and 5 years. They emerge between late April and the end of June. Like other cockchafers, they have been considered a serious pest of crops and trees.
Banksia serrata, commonly known as the saw banksia, the old man banksia, the saw-tooth banksia or the red honeysuckle and as wiriyagan by the Cadigal people, is a species of woody shrub or tree of the genus Banksia, in the family Proteaceae. Native to the east coast of Australia, it is found from Queensland to Victoria with outlying populations on Tasmania and Flinders Island. Commonly growing as a gnarled tree up to 16 m (50 ft) in height, it can be much smaller in more exposed areas. This Banksia species has wrinkled grey bark, shiny dark green serrated leaves and large yellow or greyish-yellow flower spikes appearing over summer. The flower spikes, or inflorescences, turn grey as they age and pollinated flowers develop into large, grey, woody seed pods called follicles.
Asian box turtles are turtles of the genus Cuora in the family Geoemydidae. About 12 extant species are recognized. The keeled box turtle is often included in this genus, or separated in the monotypic genus Pyxidea. Genus Cuora is distributed from China to Indonesia and the Philippines, throughout mainland Southeast Asia, and into northern India and Bhutan.
Melolonthinae is a subfamily of the scarab beetles. It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae.
Macrodactylus subspinosus is a North American beetle of the family Scarabaeidae. The members of its genus are known as "rose chafers", not to be confused with the European rose chafer, Cetonia aurata. M. subspinosus occurs from Eastern Canada to Colorado and is considered a pest of many crops and flowers. It is given its common name of rose chafer because it eats the leaves of roses, although it also feeds on many other plants.
Amphimallon solstitiale, also known as the summer chafer or European june beetle, is a beetle similar to the cockchafer but much smaller, approximately 20 millimetres (0.79 in) in length. They are declining in numbers now, but where found they are often seen in large numbers. At dusk they actively fly around tree tops looking for a mate and can often be found drowning in pools of water the following morning. They are also attracted to light and come in through open, lit windows and fly around lamps, making quite a racket while bumping into lights. They are found throughout the Palearctic region and, commonly seen from June to August, living in meadows, hedgerows, and gardens, and eating plants and tree foliage.
Zelkova serrata is a species of the genus Zelkova native to Japan, Korea, eastern China and Taiwan. It is often grown as an ornamental tree, and used in bonsai. There are two varieties, Zelkova serrata var. serrata in Japan and mainland eastern Asia, and Zelkova serrata var. tarokoensis (Hayata) Li on Taiwan which differs from the type in its smaller leaves with less deeply cut serration on the margins.
Cyclocephala lurida, the southern masked chafer, is a species of beetle in the family Scarabaeidae which is native to the southeastern United States. It is a brown beetle with a black head, with an adult length of 10 to 14 mm. The adult beetles cause no harm, but the eggs are laid underground and the developing larvae feed on grass roots and can kill turf under dry conditions.
Melolonthini is a tribe of scarab beetles in the family Scarabaeidae. There are over 250 genera in Melolonthini, occurring worldwide; there are over 300 species in North America alone, and more than 3000 worldwide.
Holotrichea consanguinea, also known as the sugarcane beetle, is a beetle belonging to the genus Holotrichia. It causes frequent problems for sugarcane growers in India.
Adoretus versutus, commonly known as rose beetle, is a species of shining leaf chafer found in Afro-Oriental tropics.
Holotrichia disparilis is a species of chafer found in Sri Lanka.
Holotrichia rufoflava is a species of dung beetle found in South India and Sri Lanka.
Holotrichia serrata, commonly known as the sugarcane white grub, or cockchafer grub, is a species of dung beetle found in India, Bangladesh, and Sri Lanka.
Cockchafer is a common name for several species of plant eating scarab beetles regarded as agricultural pests. It is most commonly used for several European species of the genus Melolontha:
