Numbers
Second largest subfamily in our area, with ca. 50 spp. in 13 genera north of Mexico(1), world's largest subfamily, with >2,000 spp. in almost 300 genera(2)
Size
Some of the smallest members to some of the largest, 5-40 mm
Identification
One of the two subfamilies (other Stenopodainae) with a quadrate cell in the corium. The second antennal segment is equal to or shorter than the first.
Range
Worldwide, incl. most of NA (some range into so. Canada & AK)

Most are found on foliage or in fields. Many are associated with flowers. Few are arboreal. Not as strongly associated with lights at night as other subfamilies.
