Leptomyrmex
''Leptomyrmex'', or spider ants, is a genus of ants and a distinctive member of the ant subfamily Dolichoderinae. Commonly known as "spider ants" for their long legs and spider-like movements, these orange and black ants are prominent residents of intact wet forest and sclerophyll habitats throughout their range. One extant species, '' Leptomyrmex relictus'', is known from central Brazil; otherwise, the global distribution of this genus is restricted to eastern Australia, New Caledonia and New Guinea, as well as the nearby Indonesian islands of Aru and Seram. Newly hatched '' Extatosoma tiaratum'' stick insects mimic these ants to avoid predation. Workers of ''Leptomyrmex'' can be easily recognized by elongate antennal scapes which surpass the posterior margin of the head by more than one half their length, a medially notched hypostoma, mandibles with 7–15 teeth and 5–12 denticles, and a laterally located anterior tentorial pit. Queens are known from only seven species. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ant Mimicry
Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive. Some arthropods mimic ants to escape predation ( Batesian mimicry), while some predators of ants, especially spiders, mimic them anatomically and behaviourally in aggressive mimicry. Ant mimicry has existed almost as long as ants themselves; the earliest ant mimics in the fossil record appear in the mid-Cretaceous alongside the earliest ants. In myrmecophily, mimic and model live commensally together; in the case of ants, the mimic is an inquiline in the ants' nest. Such mimics may in addition be Batesian or aggressive mimics. To overcome ants' powerful defences, mimics may imitate ants chemically with ant-like pheromones, visually, or by imitating an ant's surface microstructure ...

Dolichoderinae
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (''Linepithema humile''), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions. This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland. Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extatosoma Tiaratum
''Extatosoma tiaratum'', commonly known as the spiny leaf insect, the giant prickly stick insect, Macleay's spectre, or the Australian walking stick, is a large species of Australian stick insect. Range ''E. tiaratum'' is endemic to rainforests in Australia, with most of its range in eastern New South Wales and eastern Queensland, but it is also found in eastern Victoria (one old record) and South Australia (possibly introduced). The closely related and similar '' E. popa'' is from New Guinea. Description Female adult ''E. tiaratum'' are covered with thornlike spikes for defense and camouflage. Their long, rounded bodies grow to about long. The females are further described as "heavy-bodied, brachypterous and having numerous spines and integumental expansions on the face and legs, including a tuft of spines on the conical occiput of the hypognathous head". As mentioned, the wings of the female are too small for flying, especially when she is gravid. Exhibiting the sexual d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocelli
A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from " compound eyes", which have multiple lenses. They are not necessarily simple in the sense of being uncomplicated or basic. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of most large animals are '' camera eyes'' and are sometimes considered "simple" because a sing ...

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere.
