Comments

This species and the similar curve-lined angle, Digrammia continuata, closely resemble the foliage of their food plants. Of the two, only the curve-lined angle has reddish marks near the spiracles. Another common caterpillar on cedars is Taylor's cedar looper, Eupithecia intricata taylorata. This last species has continuous subdorsal and spiracular stripes, whereas the other two have broken ones. The many-lined angle formerly was known as Semiothisa multilineata.
