Formerly considered a subfamily (Caliscelinae) of Issidae.
Explanation of Names
Caliscelidae Amyot & Serville 1843
53 spp. in 8 genera in our area, ~200 spp. in ~64 genera worldwide(1)(2)
Small, cylindrical planthoppers that are brachypterous (rarely macropterous), with the wings much shorter than the abdomen. Caliscelids have a single lateral spine on the hind tibia, while issids and Gaetuliine tropiduchids typically have more.
Worldwide (Holzinger 2007); in our area, mostly c. & sw. US(1)
Most species feed on grasses
Life Cycle
Development from egg to adult averaged 68 days in a laboratory study
Planthoppers in the genus Osbornia (Tropiduchidae: Gaetuliini) are superficially similar, as the only North American planthopper taxon that also may have wings much shorter than the abdomen. Thus, Osbornia is often included in caliscelid keys.
