After feeding, it concludes its exploitation of the host by pupating in the caterpillar's pupal shell, which the caterpillar, of course, conveniently placed in the safety of the soil. The wingspan of the males is 25–30 mm. The green caterpillars feed amongst the blossom trusses from green cluster to early June.

Browse the list of datasets and find organisations you can join if you are interested in participating in a survey for species like Operophtera brumata (Linnaeus, 1758) They can severely reduce yields and/or defoliate bushes. Data were supplemented with similar data from 1964 to 1966 and historical information. The larvae feed on a range of trees and shrubs, as well as moorland species such as heather (Calluna). This is a classical example of how life tables can be used to describe and understand population fluctuations over time. The neonates primarily feed on the buds and nearly unfurled leaves of sugar maple, American beech and trembling aspen. Similar species: The winter moth looks very similar to the fall cankerworm (Alsophila pometaria) in both adult (Figure 8) and larval (Figure 9) stages. Both comments and pings are currently closed.
