Lycidae (net-winged beetles; subclass Pterygota, order Coleoptera) Family of brightly coloured, distasteful beetles, 5–20 mm long, which are often mimicked by harmless insects. The elytra have pronounced longitudinal ridges. The pronotum is expanded and ridged, covering most of the head. The antennae are long and thick, often serrate or pectinate, and placed close together on the head. The eyes are protuberant. Some are sexually dimorphic, with larviform females. Larvae are usually found in dead trees. Their antennae are much reduced. Both adults and larvae are predatory. There are 3000 species, mostly tropical.

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.
