Zygina is a complex genus, most with a distinctive red zig-zag pattern covering the forewings. The patterns are variable, and identification can be difficult; care must be taken to look at the right combination of features and microscopic confirmation is necessary in some cases. Females may not be identifiable.
Z. angusta is a very variable species, and difficult to separate from Z. ordinaria. The male hind tarsus is less than half the length of the hind tibia and the apical segment and apical half the of middle segments are dark. The scutellum tends to be mostly brown, with the anterior corners and sometimes the midline pale. The clavus is darkened between the red bands (unlike Z. flammigera), the extent of which varies greatly.
Found commonly on various trees, overwintering on evergreens.
