Parks and gardens where the foodplants Monterey cypress and Leyland cypress occur. The moths fly in May and June, with a second generation in August and September. It feeds on Monterey cypress and Leyland cypress. First found in West Sussex in 1984, this species has now become established in parts of southern England, such as the Isle of Wight, Hampshire and Dorset and may be spreading north.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Thera cupressata. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
