Straw belle moth biology

The straw belle moth is a resident of the UK. It normally flies at dusk but, if disturbed, will fly during the day. The moth emerges in July and is on the wing until August. The eggs are laid on a number of different chalk grassland plants including, thyme, cinquefoil and wild parsnip.

The caterpillars hatch in September and spend the winter as very small larvae, re-emerging in spring. They pinvertebrates_freshwater

Straw belle moth threats

This species has declined severely in recent decades, chiefly through loss of its habitat. This has been caused by a number of factors including road construction, housing and industrial development, and especially agricultural improvement to the calcareous grassland, which reduces the numbers of wildflower species. There has also been a decline in the traditional forms of grazing which have also led to habitat changes. There have been a number of cases of accidental and deliberate burning of the grasslands which sinvertebrates_freshwater

Straw belle moth conservation

As a result of the decline of the straw belle moth in the UK, it was introduced into English Nature's Species Recovery Programme. It is also listed as a UK Biodiversity Action Plan (UKBAP) priority species. In partnership with Butterfly Conservation, English Nature have drawn invertebrates_freshwater The remaining sites where the moth is found are all declared Sites of Special Scientific Importance (SSSIs) and the management agreements for these sites reflect the habitat requirements of the species. Two agri-environment schemes are available for landowners to encourage appropriate management of these sites and the aim is to achieve this by the year 2005. It is also hoped that by restoring other sites within the moth's former range, a re-introduction programme might be possible. Survey work, with the aim of identifying suitable locations and achieving the right type of land management, is invertebrates_freshwater

    Agri-environment schemes
    These schemes allow the government to compensate farmers for using methods that benefit the environment. The two main initiatives in the UK are the Countryside Stewardship Scheme and Environmentally Sensitive Areas. Since October 2000 these have formed part of the England Rural Development Programme (EDRP), administered by DEFRA, the Department of Environment Food and Rural Affairs. For more on these initiatives see: http://www.defra.gov.uk/erdp/erdphome.htm
