Hind tibia with movable spur. The spur is large, distinctly larger than the teeth that are also at the end of the tibiae. Delphacids are mostly small insects, usually between 2-4 mm (but range 1.5 - ~7mm). The wings are membranous or somewhat thickened (especially when brachypterous), and held tent like; the wings may be clear or patterned. Among the planthoppers, the family Delphacidae is most easily recognized by examining the hind legs. | |
