Insects (from Latin insectum, a calque of Greek ἔντομον [éntomon], “cut into sections”) are a class within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are among the most diverse group of animals on the planet and include more than a million described species and represent more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing metazoan life forms on Earth. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans.

Mating pair of Sphecius grandis
Sphecius grandis, also called the western cicada killer, is a colony-forming species of wasp in the genus Sphecius (cicada killer wasps). It shares the same nesting biology as its congener the eastern cicada killer, S. speciosus. S. grandis, like all other species in the genus, mainly provides cicadas for their offspring. It is colonial, mating brooding once a year, in July and early August. Adults are typically 3–5 cm (1.2–2.0 in) long, and amber-yellow with yellow rings on the abdomen.

Members of the genus Sphecius are not habitually aggressive and save their venom for cicadas which they paralyse and take back to their nests. The female catches around four or more cicadas for provisioning, places them in her brood cells and then proceeds to lay eggs in her cells. The species is endemic to Central America and the Western United States, and is found at a higher mean altitude than other species of Sphecius. The males emerge earlier than females, but generally die after only a couple of days.

Things you can do

  • Create articles: There are thousands of family-level through species-level articles that have yet to be started... Pick your favorite and start researching!
  • Find photos for articles: 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!
  • Add or update a {{Taxobox}}: Add more information like species authors or create a completely new taxobox for an entomology article that needs one!
  • Categorize articles: 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.
