Status – Cliff tiger beetle
Classified as Rare in Great Britain (3).
Description – Cliff tiger beetle
Range – Cliff tiger beetle
This beetle was once distributed along the coast of England between Hampshire and Devon, and also occurred in South Wales, with unconfirmed historical records from Berkshire and Kent. However, it has only been found in Dorset and on the Isle of Wight since 1970. Outside of Britain, it has a wide distribution from western Europe reaching east to China (3).
Habitat – Cliff tiger beetle
Lives on coastal cliffs, or near their bases, on bare or sparsely vegetated sand or silt close to seepages of freshwater (3).
Biology – Cliff tiger beetle
The life cycle of this tiger beetle takes a year to complete; adults breed in the summer, larvaehibernate during winter in vertical burrows in sand or silt, and adults emerge the following spring (3). The larvae and adults are predatory, hunting invertebrates that are active on the surface, particularly ants (3). This species rarely flies; instead it moves around by running rapidly over sand (4).
Threats – Cliff tiger beetle
The threats facing this beetle include coastal erosion and development, cliff stabilisation programmes, as well as the growth of scrub (3).
Conservation – Cliff tiger beetle
The cliff tiger beetle is a UK Biodiversity Action Plan (UK BAP) priority species; its Species Action Plan aims to maintain all current populations, and ensure that new populations are established in at least 5 sites within the historic range before 2010 (3). This beetle receives some protection, as some sites in which it occurs are designated Sites of Special Scientific Interest (SSSIs) or National Nature Reserves (NNRs) (3). Furthermore, English Nature has included the cliff tiger beetle in its Species Recovery Programme.

Glossary
- Elytra: in beetles and earwigs, the hard fore wings. They are held aloft when the insect flies, and are often coloured or patterned.
- Hibernate: a winter survival strategy characteristic of some mammals in which an animal's metabolic rate slows down and a state of deep sleep is attained. Whilst hibernating, animals survive on stored reserves of fat that they have accumulated in summer. In insects, the correct term for hibernation is 'diapause', a temporary pause in development and growth. Any stage of the lifecycle (eggs, larvae, pupae or adults) may enter diapause, which is typically associated with winter.
- Larvae: stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
