Label abbreviation explanations

Up to three sets of names are given below: the first in accord with the terminology of the Manual of Nearctic Diptera[1]; the second with the older system of Williston; and the third with the Comstock-Needham system. In many instances, the MND and Comstock-Needham terminology coincide, in which case the latter aren't repeated below. All three naming systems are commonly encountered in the literature and elsewhere.

  c = costal cell. This is the sliver-thin cell along the leading edge of the wing, spanning the basal half or more of its length.
                          The costal cell consists of two subcells: namely the 1st costal cell and the 2nd costal cell.
                          The 1st costal cell is the short portion of the costal cell basad to the humeral cross-vein,
                          while the 2nd costal cell is the much longer portion distal to the humeral cross-vein.
  br = basal radial cell; also called the 1st basal cell by Williston.
  bm = basal medial cell; also called the 2nd basal cell by Williston.
  cup = posterior cubital cell; also called the anal cell by Williston; and the 1st anal cell by Comstock-Needham.
  dm = discal medial cell; or simply the discal cell per Williston; and the 1st M2 in the Comstock-Needham system.
  r1 = cell posteriorly adjacent to the 1st radial vein R1; also called the marginal cell by Williston.
  r2+3 = cell posteriorly adjacent to the vein segment "R2+3", which is considered the fusion of the 2nd and 3rd radial veins
              of the more basic (i.e. less modified and evolutionarily reduced) dipteran wing plan.
              Also called the 1st submarginal cell by Williston.
              It is sequentially the the "2nd radial cell", but referred to as cell R3 in the Comstock-Needham system.
  r4+5 = cell posteriorly adjacent to the vein segment "R4+5", which is considered the fusion of the 4th and 5th radial veins
              of the more basic (i.e. less modified and evolutionarily reduced) dipteran wing plan.
              Also called the 2nd submarginal cell by Williston.
              It is sequentially the the "3rd radial cell", but referred to as cell R5 in Comstock-Needham.
