Dipteran is a word used to describe insects that have two wings, such as flies and mosquitoes. However, there are various other synonyms used by entomologists to describe these same types of insects. Some common synonyms include "two-winged insects," "true flies," "muscoid flies," and "flies and midges." Other terms used more specifically for certain types of dipteran include "culicids" for mosquitoes, "simuliids" for black flies, and "tabanids" for horse flies. Using synonyms can be useful for more precise communication in the scientific community, and can help to avoid confusion when discussing specific insect species.
