Insects (from Latin insectum) are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. (Full article...)

Chrysiridia rhipheus, the Madagascan sunset moth or simply sunset moth, is a day-flying moth of the Uraniidae family. It is considered to be one of the most impressive and beautiful Lepidoptera, though the iridescent parts of the wings appear coloured through optical interference rather than pigments. Adult moths have a wingspan of 7–9 centimetres (2.8–3.5 in). It is endemic to Madagascar, where it is found throughout the year in most parts of the island, with peak populations between March and August.

Females lay about 80 eggs under the leaves of Omphalea spp. The caterpillars are whitish-yellow with black spots and red feet and are covered in club-ended black setae. Silk spun from the mouth helps the caterpillars hold on to smooth leaves and climb back to the plant when they fall. After completing four instars, the caterpillars spin an open network cocoon. The pupal stage lasts from 17 to 23 days. Chrysiridia rhipheus is the sole specialist herbivore of the four species of Omphalea in Madagascar. Omphalea is toxic: the toxins are sequestered by the feeding caterpillar and retained in the pupal and adult stages. Thousands of these moths migrate between the eastern and western ranges of their host plants.

Things you can do


Here are some tasks awaiting attention:
  • Article requests : There are thousands of family-level through species-level articles that have yet to be started.
  • Categorization : Figure out what categories to add to each article so that others can find them more easily. Also use the {{WikiProject Insects}} template to classify the status of any articles related to insect taxa.
  • Infobox : Add or update a {{Taxobox}}: Add more information like species authors or create a completely new taxobox for an entomology article that needs one.
  • Photo : Many entomology–related articles would be substantially better with the addition of one or more photographs. Feel free to take your own and upload them, or find ones with the appropriate licenses and upload them here.

Gryllotalpa brachyptera is a mole cricket (Orthoptera: Gryllotalpidae), native to Australia. Mole crickets are thick-bodied insects about 3–5 cm (1.2–2.0 in) long, with large beady eyes and shovel-like forelimbs highly developed for burrowing and swimming. The adult mole cricket may fly as far as 8 kilometres (5.0 mi) during the mating season, is active most of the year, and spends the winter in hibernation.
