Behavior
The herald's flight period is between June and November, in one or two broods. During the winter the herald moth hibernates in dark, cool structures , returning to take wing again from March to June. Its habitat is woodland parks and gardens, and the resting wing pattern resembles a dead, shriveled leaf.Herald caterpillars are a bright green shade common to many caterpillars. They are distinguished by the thin yellow lines running across the body between segments. When maturity is reached, they pupate between two leaves, in a white cocoon made of silk.
