In some taxonomies Calyptratae is ranked as a zoosubsection, in others a subsection, a section, or an unnamed rank, sometimes but not always called a clade. MinnesotaSeasons.com follows iNaturalist in using the rank zoosubsection. In any of these classifications, Calyptratae include those flies that have calypters at the base of the wing.

There are about 18,000 Calyptratae species worldwide, including the common house fly and other well-known flies. The zoosubsection is divided into three superfamilies. All three subfamilies occur in Minnesota.

 
           
 
Description
 
 

Calyptrate flies have a pair of membranous lobes (calypters) at the base of each wing that covers the balancing structure (haltere). This is the feature that gives the zoosubsection its common name. The lower calypter on each side is usually prominent. The antennae have three segments. The second segment has a longitudinal groove (suture) on top.

The families are distinguished by the body type, the arrangement of bristles, the pattern of wing veins, and the shape of the proboscis.
