Grasshoppers, crickets & allies

21 of the 26 native UK species have been recorded on Dawlish Warren, this makes it one of the most outstanding sites in the UK. The wide range of habitats and the mild climate all combine to create the conditions for a wide variety of species.  It is hoped that the following information will help recording these species on site. Please submit any sightings to the Recording Group and/or Devon Biodiversity Records Centre.

Species

Oak Bush-cricket                         Meconoma thalassinum
This species is present in the Entrance Bushes and in other wooded areas on site. Individuals have been found on the Visitor Centre and attracted to moth traps.

Great Green Bush-cricket          Tettigonia viridissima
This Devon priority species is widespread on site, especially in areas of bramble scrub. The loud stridulation easily reveals its presence, but despite its large size they can be surprisingly difficult to locate.

Dark Bush-cricket                       Pholidoptera griseoaptera
This common species is widespread in south Devon, but despite searching, was rare in the Recording Area. A single second or third instar individual was recorded near the First Pond in 2000. However in 2008 several adults and individuals in various instars were found in a large patch of Restharrow and it is now regular on site.

Grey Bush-cricket                       Platycleis albopunctata
This is a predominately coastal species which can be found on sand dunes and cliffs along most of the southern coast of England. A single large instar was recorded here in 1993, but there were no further records. This individual was seen whilst planting trees in the Buffer Zone so might have been introduced on them.
However in 2008 several individuals in various instars were found, with several further records so the species is indeed native on site.

Roesel's Bush-cricket                 Metrioptera roeselii
A macropterous (long winged) male was discovered in the Back Meadow in July 2018, just the third Devon record for this species. Expanding westwards, 2018 saw several more Devon records and it may soon become established in the County and perhaps even on site.

Long-winged Conehead             Conocephalus discolor
This species is a recent arrival in the recording area, with individuals first being noted in Greenland Lake in the mid 1990s. Since then a good population has built up and it can be found in most areas of long grassland.

Short-winged Conehead             Conocephalus dorsalis
A single female was recorded in the Buffer Zone in September 2005, previous records of instars had not ruled out the above species. Adults were also recorded in the saltmarsh in August 2008 & 2020, but this remains by far the rarer of the two species present.

Speckled Bush-cricket               Leptophytes punctatissima
A single adult individual, recorded in the Dogwood clump on Warren Point, in 1996 was the first record, but this species was expected to occur elsewhere on site. This prediction was finally confirmed when a late instar was recorded in July 2008 with regular records since then.

Cepero’s Ground-hopper          Tetrix ceperoi
Has been recorded around the Entrance Bushes and Greenland Lake, although never in numbers. This is one of the few sites in south Devon for this nationally rare species but has not been seen recently.

Slender Ground-hopper          Tetrix subulata
Discovered in Greenland Lake in April 2009, no doubt overlooked previously, this species is still present, but scarce.

Common Ground-hopper           Tetrix undulata
This species is found in similar areas to its rarer relatives, often in good numbers. It is the only native orthopteran that can be found at all times of year.

Common Field Grasshopper      Chorthippus brunneus
A widespread species that is commonly found on site. If disturbed adults can fly good distances to escape.

Meadow Grasshopper                Chorthippus parallelus
Another widespread and common species, this is the most numerous grasshopper on the Warren.

Lesser Marsh Grasshopper       Chorthippus albomarginatus
This species is rare in the southwest and this is one of the few sites it occurs in Devon. Several individuals have been recorded in the saltmarsh at the back of the Golf Course. Elsewhere on the Exe, it is also recorded at Exminster Marshes and the Old Sludge Beds.

Rufous Grasshopper      Gomphocerippus rufus
The first Devon record of this nationally rare species was found here by Parfitt in 1881. Unfortunately it has long been extinct on site.

Mottled Grasshopper                 Myrmeleotettix maculatus
This species prefers areas of short sun-baked turf, especially inward of the Dune Ridge,
there are few recent records.

Dusky Cockroach                        Ectobius lapponicus
Dawlish Warren is one of very few sites were this species can be found in Devon. It has been recorded on Warren Point, but presumably occurs elsewhere on site.

Tawny Cockroach                        Ectobius pallidus
Like Dusky, this species is rarely recorded in Devon. Here it is recorded more frequently than the above species, it has regularly been found at moth traps.

Lesser Cockroach                       Ectobius panzeri
The most frequently encountered of the three native cockroaches in the Recording Area. It can be particularly numerous in the short grass on Warren Point.

Common Earwig                           Forficula auricularia
As elsewhere this species can be encountered almost anywhere on site.

Lesne’s Earwig                             Forficula lesnei
One found by John Walters near the car park in October 2003 was the first record. It is still present there and in the Entrance Bushes, over wintering in umbellifer stems.
