Dryinidae (suborder Apocrita, super-family Bethyloidea) Family of small (1.5–10 mm long), black, parasitic wasps in which the fore tarsi of the female are often chelate and used to grasp the host adult or nymph. The host is stung and becomes insensible, whereupon the female wasp lays her egg or eggs. The larvae are mostly ectoparasitic on the abdomens of adult or nymphal plant hoppers, leaf hoppers, and tree hoppers. The position of the parasite on the host varies; more than one may be present; and many species exhibit polyembryony, with up to 60 individuals resulting from a single fertilized egg. The family is relatively uncommon.

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.
