Study species
Tettigetta isshikii (Hemiptera: Cicadettinae) is a small cicada
species distributed across East Asia, including Korea, Russia (Sakhalin,
Ussuri, and Siberia), and China (Lee 2008) (Figure 2A). In Korea,T. isshikii is widespread on the mainland but not on the small
islands, except for Jeju Island (Lee 2008). The species is found at
various altitudes, ranging from 30 metres to as high as 1,000 metres
(Lee et al. 2004; Jiman Heo, personal observation). Since T.
isshikii adults feed on xylem sap from herbaceous plants and lay eggs
in the stem of herbaceous plants, they are rarely found on trees (Jiman
Heo, personal observation). During the day, adult male T.
isshikii produce long calls to attract females, but they remain silent
at night (Lee et al. 2004; Jiman Heo, personal observation).
