Metaxinidae
''Metaxina'' is the only genus in the beetle family Metaxinidae. Its only species is ''Metaxina ornata''. It endemic to the South island of New Zealand, where it is associated with sooty mold growing on '' Nothofagus'' trees. Both the larvae and adults are likely predaceous, feeding on insects and other arthropods. It is considered to be a member of the superfamily Cleroidea. Genetic studies have suggested that ''Metaxina'' should be considered a member of Chaetosomatidae Chaetosomatidae is a small family of beetles, in the superfamily Cleroidea Cleroidea is a small superfamily of beetles containing over 10,000 species.

Cleroidea
Cleroidea is a small superfamily of beetles containing over 10,000 species. Most of the members of the group are somewhat slender, often with fairly soft, flexible elytra, and typically hairy or scaly. Description Cleroidea is defined by the following features: adult and larva with mandibular mola absent, larva with basal mandibular process (lacinia mobilis) present), and mala with a pedunculate seta present. Some cleroids, especially in Cleridae and the melyrid subfamily Malachiinae, have bright aposematic colouration to deter predators. They mimic the appearances of other arthropods that are unpalatable to predators, such as various beetles ( blister beetles, leaf beetles, net-winged beetles), stinging Hymenoptera (ants and velvet ants), zygaenid moths and tachinid flies. There is variation in the degree of sclerotisation within Cleroidea. Some are hard-bodied beetles with fully sclerotised elytra that match the shape of the abdomen (Trogossitidae, Lophocateridae, Peltidae ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooty Mold
Sooty mold (also spelled sooty mould) is a collective term for different Ascomycete fungi, which includes many genera, commonly ''Cladosporium'' and ''Alternaria''. It grows on plants and their fruit, but also environmental objects, like fences, garden furniture, stones, and even cars. The mold benefits from either a sugary exudate produced by the plant or fruit, or honeydew-secreting insects or sap suckers the plant may be infested by. Sooty mold itself does little if any harm to the plant. Treatment is indicated when the mold is combined with insect infestation. Description Sooty mold is a collective, self-descriptive term for a number of different fungi; it is a black, powdery coating adhering to plants and their fruit or environmental objects. Biology The ecology of the different species, their interactions, relationship to the host are little understood. A chance observation of a '' Microcyclospora tardicrescens'' inhibiting the growth of the fruit pathogen ''Colletot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothofagus
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clonal rep ...

Most of the members of the group are somewhat slender, often with fairly soft, flexible elytra, and typically hairy or scaly. Description Cleroidea is defined by the f .... There are three extant genera, two of which ('' Chaetosoma'' and '' Chaetosomodes)'' are endemic to New Zealand with the other ('' Malgassochaetus)'' native to Madagascar. Members of this family are predaceous on wood-boring insects.
