Idaea
wave moths, dwarf geometer moths
Idaea is a large genus of geometer moths (Geometridae: Sterrhinae) distributed nearly worldwide. The genus contains numerous small species, many of which are characterized by wavy transverse lines on the forewings that give them their common name of 'wave moths.' Species diversity is particularly high in the Mediterranean region, African savannas, and the deserts of western Asia. The genus was established by Treitschke in 1825.
