The arthropods portal

Arthropods make up the largest phylum of animals (Phylum Arthropoda) and include the insects, arachnids, crustaceans and others. More than 80% of described living animal species are arthropods, with over a million modern species described and a fossil record reaching back to the late Proterozoic era. Arthropods are common throughout marine, freshwater, terrestrial, and even aerial environments, and includes various symbiotic and parasitic forms. They range in size from microscopic plankton (~¼ mm) up to forms several metres across. Arthropods are characterised by the possession of a segmented body with appendages on each segment. They have a dorsal heart and a ventral nervous system. All arthropods are covered by a hard exoskeleton made of chitin, a polysaccharide which protects against trauma and desiccation. They shed this covering periodically when moulting.

Abantiades latipennis, known as the Pindi moth, is a species of moth in the Hepialidae family. Endemic to Australia and identified in 1932, it is most populous in temperate rainforest where eucalypts are prevalent, as the larvae feed primarily on their roots. Females lay eggs during flight in a scattering fashion. The larvae live for over eighteen months underground, while adult moths survive for approximately one week, as they have no mouthparts with which to feed. The moths are preyed upon by a number of predators, including bats and owls. Brown in colour overall, males are paler and the identifying silver bars of the male's wings are more prominent than those of the females, with dark margins. Male adults are generally smaller.

Established clearfelling practices have been shown to favour the Pindi moth, and could lead to it being considered a pest due to opportunistic proliferation of the species. The resulting damage caused to the trees on which it feeds may be considered significant.

To do

Here are some tasks you can do:

  • Start a new article. Arthropods cover an huge range of taxa and other topics, so there will always be plenty of missing articles. Some which have been explicitly requested are listed here.
  • Clean up existing articles. Lists of articles needing cleanup are available either grouped by the work needed or ungrouped.
  • Expand an existing article. Existing articles are often incomplete and missing information on key aspects of the topic. It is particularly important that the most widely read articles be broad in their scope. Wikipedia:WikiProject Arthropods/Popular pages (updated monthly) shows the number of views each article gets, along with assessments of its quality and importance. Articles with higher importance ratings and greater numbers of views are the priority for article improvements, but almost all our articles would benefit from expansion. Stubs can be found in Category:Arthropod stubs and its subcategories.
