The Insects Portal

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...)

Notoligotoma nitens

The order Embioptera, commonly known as webspinners or footspinners, are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. More than 400 species in 11 families have been described, the oldest known fossils of the group being from the mid-Jurassic. Species are very similar in appearance, having long, flexible bodies, short legs, and only males having wings.

Webspinners are gregarious, living subsocially in galleries of fine silk which they spin from glands on their forelegs. Members of these colonies are often related females and their offspring; adult males do not feed and die soon after mating. Males of some species have wings and are able to disperse, whereas the females remain near where they were hatched. Newly mated females may vacate the colony and establish a new one nearby. Others may emerge to search for a new food source to which the galleries can be extended, but in general, the insects rarely venture from their galleries. (Full article...)

Simosyrphus grandicornis is an Australasian species of hoverfly (Diptera: Syrphidae), and is one of the two most common hoverflies in Australia, alongside Melangyna viridiceps. Pictured above is a pair of S. grandicornis mating in flight.

Tasks

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.
