Dingy mocha moth status

Classified as Rare in Great Britain (2).

Dingy mocha moth threats

Factors contributing to the decline of this species may include the loss of suitable habitat. Heathland has been lost due to development, forestry and agricultural intensification; furthermore, poor management may result in succession to woodland. Heathland fires and scrub clearance during heathland restoration may also put pressure on this moth (2).

Dingy mocha moth conservation

The Dingy Mocha has been targeted as a priority species for conservation under the UK Biodiversity Action Plan (UK BAP). The aims of the Species Action Plan are to maintain and enhance all known populations, and to restore the species to five sites in its former range by 2010 (2). Research into the ecology of the species and a regular monitoring programme have also been recommended (2).

The UK Biodiversity Action Plan for this species is available at UK BAP.
There may be further information about this species available via the National Biodiversity Network Gateway.

Glossary

Bivoltine
(also known as 'double-brooded'). Insect life cycle that takes 12 months to complete, but involves two generations in that time. The first generation adults lay eggs that give rise to those of the second generation. The second generation overwinters either as an egg, larva, pupa or adult.
Pupa
Stage in an insect's development when huge changes occur, which reorganise the larval form into the adult form. In butterflies the pupa is also called a chrysalis.
Succession
The progressive sequence of changes in vegetation types and animal life within a community that, if allowed to continue, result in the formation of a 'climax community' (the last stage in a succession where the vegetation reaches equilibrium with the environment).
