Distribution


Imago

Wingspan 19–19 mm.
Note: Chlorissa viridata and Chlorissa cloraria are genetically related. The external features and also the genital differences are not always reliable! However, one of the best characters is the costa of the forewing which in Chlorissa cloraria always has some brown scales (best visible on the underside), while in Chlorissa viridata the costa is concolorous with the groundcolour of the forewing or even brighter. Also, the whitish postdiscal line is sinuous in Chlorissa cloraria, while it is almost straight in Chlorissa viridata.
