Molossidae (free-tailed bats; order Chiroptera, suborder Microchiroptera) A family of insectivorous bats in which the thick tail is surrounded by the uropatagium which forms a loose sheath, and projects below the edge of the uropatagium when the animal is at rest. The nose is simple, with no leaf, and in most species overhangs the jaw. The ears are heavy-looking and deeply folded. Molossids often form very large colonies in caves and roofs. They are of world-wide tropical and subtemperate distribution. There are about 12 genera, with about 90 species.

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.
