Phasmatidae (stick insects, walking sticks; subclass Pterygota, order Phasmatodea) Family of large to very large insects, whose common name refers to their resemblance to twigs: this resemblance is often striking and is enhanced by their habit of swaying slowly from side to side. When disturbed, stick insects may become cataleptic and fall to the ground, or else rustle and expand brightly coloured hind wings. They may also produce repugnant odours and secretions. Almost all of the 2000 or so species are found in warmer regions of the world, although two species from New Zealand have established themselves in the Isles of Scilly (Great Britain).

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
