Explanation of Names
From Latin nemus meaning woodland or grove (1). Various forms and derivatives are nemoris, nemoralis, nemoral, of a woodland. Apparently related to or derived from Greek nemos (νεμος) a pasture or wooded pasture (2) (Wiktionary--nemus). This refers, presumably, to the habitat and/or the typical green color of the wings.
Numbers
Friends Central Science--Geometrinae, following Ferguson (1985) lists about 38 species.
Size
typically 20-25 (30) mm
Identification
Medium-sized moths with rounded to angular wings and faint white lines, typically striking green, and often with red and iridescent highlights. Some species show seasonal polyphenism. Compare brown (typical of spring) and green (typical of summer) forms of Nemoria bistriaria:
Life Cycle
