Cord: In insect wings, the cord (sometimes also spelled chord, or referred to as the anastomosis) is an apparent, jagged, transverse line across the wings where the major crossveins align with the bases of the main forks of the longitudinal veins. It is especially noteworthy as an identifying characteristic in caddisfly forewings.
