The family of the insect order Hemiptera having loop veins in forewing is Miridae.
The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae.
One useful feature in identifying members of the family is the presence of cuneus, it is the triangular tip of the corium, the firm, horny part of the forewing, the hemelytron.
The cuneus is visible in nearly all Miridae, and only in a few other Hemiptera, notably the family Anthocoridae, which are not much like the Miridae in other ways.
