|Crickets and Grasshoppers in Nottinghamshire|
|Grasshoppers are among some of the
best known insects, but as many species are difficult to
observe closely, they are often not seen well enough to
identify. To make matters more difficult, there are
considerable variations within some species, which is
another factor hindering those wishing to identify them.
A net is therefore recommended for capture and study.
They belong to the order Orthoptera, of which there are four main families including Grasshoppers, Groundhoppers, Bush Crickets and True Crickets.
The current UK list contains around 30 species, including some known migrants/accidentals. Recent years have seen an exciting period for Orthoptera and our increasingly warmer climate has allowed several species expand their UK ranges.
recent Nottinghamshire colonists
Three of the species expanding their UK ranges, promptly arrived in Nottinghamshire after the turn of the century and increasing Nottinghamshire's present Orthoptera fauna list to 15 species.
Lesser Marsh Grasshopper (Chorthippus albomarginatus) was the first of the three to appear here in 2000. Roesel's Bush Cricket (Metrioptera roeselii) arrived in 2006 and beat our first Long-winged Conehead (Conocephalus discolor) by a matter of weeks. Since arriving, all three species have spread to reach most parts of Nottinghamshire by the end of 2011. But these have not been the only new Crickets or Grasshoppers to appear in recent years.
The Southern Oak Bush Cricket (Meconema meridionale) was recorded for the first time (twice) from a Bilborough garden in 2009, but we have no further information regarding any subsequent records of this Bush Cricket in Nottinghamshire, but it should be looked for anywhere. Our most recent addition however, was the Short-winged Conehead (Conocephalus dorsalis) in 2011 and originally discovered at Attenborough Nature Reserve by Richard Rogers, before a quick follow-up record from Gunthorpe by Roy Frost. The Short-winged Conehead's range-expansion looks likely to continue over the next few years.
|Rare and scarce
Despite much success for our most Nottinghamshire Orthoptera, two species still remain genuine county rarities and one may have disappeared altogether.
Perhaps the most restricted species in the county is the Stripe-winged Grasshopper (Stenobothrus lineatus) which is still only to be found at Budby South Forest. It's occurrence here is especially interesting, as this is a relatively isolated site and in one of just three 10Km grid squares, north of a line between the Wash and the Severn estuary as far as we know.
Having a largely southerly UK distribution at coastal sites, Cepero's Groundhopper (Tetrix ceperoi) is apparently known from just a handful of Nottinghamshire sites and remains difficult to record, due to its close similarity to the commoner Slender Groundhopper.
The Speckled Bush Cricket (Leptophyes punctatissima) is now known from at least five sites in Nottinghamshire, but is probably still under-recorded and could be slowly increasing it's range here.

Cricket (Acheta domesticus) is
a non-native species and very rarely reported now, but it
is the Dark Bush Cricket (Pholidoptera
griseoaptera) that may have fared worst out of all
Nottinghamshire's Orthoptera. The last known
record was from the Bingham Linear Park in 2003, where it
were last recorded by Paul Waring. Nottinghamshire's Orthoptera
recorder Roy Frost, conducted an unproductive search for
this species here back in August 2011 and although the
site still contains suitable habitat, it is feared that
the Dark Bush Cricket has possibly been lost.
Our thanks must go to Roy Frost (the Orthoptera recorder for Nottinghamshire) for providing information regarding the status of some of the rarer Crickets and Grasshoppers across Nottinghamshire.
|Long-winged Conehead Conocephalus discolor|
|A recent colonist, Nottinghamshire's first record of this rapidly spreading species came in 2007 when it was discovered at Keyworth Meadow in the far south of the county. It subsequently spread rapidly, being found at Attenborough Nature Reserve and north-east up the Trent Valley within the space of a few years. In August 2011, it was discovered at Shirebrook Pit Wood and Lound Gravel Pits near Retford, so the Long-winged Conehead is obviously widespread in Nottinghamshire now. Both sexes are fully-winged and the wings reach beyond the end of the abdomen in adults.|
|Oak Bush Cricket Meconema thalassinum|
|The Oak Bush Cricket is probably fairly commonly distributed across much of Nottinghamshire and it is often attracted to lights left on overnight. One such record came from Eakring village Post Office, but this quite large green Bush Cricket is relatively easy to find by searching the trunks of trees or beating foliage in wooded areas during the Summer and Autumn months. Adults and nymphs are regularly recorded from Budby South Forest and at other Sherwood Forest sites.|
|Speckled Bush Cricket Leptophyes punctatissima|
|The Specked Bush Cricket is still quite a rarity in Nottinghamshire, being recorded from just a handful of sites. Like many Orthoptera, this is probably due to under-recording, rather than being actually locally scarce. Our first records actually came from a suburban garden on Sandford Road in Mapperley Nottingham, before finding a previously unkown colony, situated along a forest track leading to Budby South Forest in 2009. The adults can be looked for during August, but are often extremely difficult to see amongst low foliage, even though good numbers may be present at a site. Both sexes have short wings.|
|Dark Bush Cricket Pholidoptera griseoaptera|
|This large Cricket has possibly died out, with no Nottinghamshire records since 2006. In the south of the UK, Dark Bush Cricket is common and we found them to be numerous on Brambles growing on a former landfill site at Dartford, Kent. Seeing the rank habitat there, makes you wonder if this species is just under-recorded in Nottinghamshire.|
|Roesel's Bush Cricket Metrioptera roeselii|
|Roesel's Bush Cricket first arrived in Nottinghamshire in 2006 when it was found by the A453 near Clifton. By the following year, it was found at Collingham, Stoke Bardolph and Langford Lowfields and has continued it's north-westerly spread since, reaching the Nottinghamshire/Derbyshire border at Shirebrook Pit Wood by 2011. The high-pitched sound made by the male is difficult to hear, but we have found them even more difficult to actually see. The Roesel's Bush Cricket is usually brown, although a green form does occur. A broad cream margin runs around the sides of the pronotum, and there is a series of three pale yellow spots on the sides of the thorax. Short-winged and flightless, but a fully-winged form does occur in hot Summers.|
|Field Grasshopper Chorthippus brunneus|
|The commonest and most widespread Grasshopper, the Field Grasshopper is the most likely species to wander well into urban gardens. Overall, this Grasshopper is a mixture of shades of brown and the sharply incurved pronotal side-keels a key identification feature. Both male and female are fully winged.|
|Lesser Marsh Grasshopper Chorthippus albomarginatus.|
|The Lesser Marsh Grasshopper first appeared in Nottinghamshire in 2000 and is now a widespread and common species at many grassy sites in the county. Very similar in appearance to the Meadow Grasshopper, the Lesser Marsh Grasshopper is a more dull coloured species, usually being straw or light green-coloured and distinctly less bright green than Meadow Grasshopper. The almost parallel side keels of the pronotum, are a good pointer towards identification and this Grasshopper is fully-winged, though rarely reaching the end of the abdomen.|
|Meadow Grasshopper Chorthippus parallelus|
|A very common Grasshopper of grassy areas. Adults are green-coloured but often with brown wings and some adults can be entirely brown. The side-keels of the pronotum are only very slightly incurved. Some adult females and nymphs can be vivid pink/purple. Male Meadow Grasshoppers are fully-winged, but the females are usually short-winged, though fully-winged females can occur.|
|Common Green Grasshopper Omocestus viridulus|
|A common species in grassy areas. This is another of the largely green or green and brown Grasshoppers, but there is never any red or orange colouration on the abdomen, a feature which helps towards identification. Adult females are green along the top of the head and pronutum, though can be green, brown or even bright purple elsewhere. The side-keels of the pronotum are gently incurved. Both sexes are fully-winged.|
|Mottled Grasshopper Myrmeleotettix maculatus|
|The Mottled Grasshopper is restricted in Nottinghamshire to some heathland sites, though we have personally only found it at Budby South Forest and more recently at Sherwood Heath SSSI. Even at Budby, it can be quite a difficult Grasshopper to find, seeming to prefer sparsely vegetated ground with heather re-growth. Identification of Mottled Grasshopper is relatively easy (despite there being many named colour forms), simply by checking for the clubbed antennae which is characteristic of this species.|
|Stripe-winged Grasshopper Stenobothrus lineatus|
|This is a rare and restricted Grasshopper in Nottinghamshire and the Midlands. As far as we know, in Nottinghamshire, it is still only found at Budby South Forest. The Stripe-winged Grasshopper being in Nottinghamshire is quite an interesting fact in itself, as it is extremely isolated from most other UK sites where this Grasshopper is found. All other sites except two in Yorkshire, lie south of a line between the Wash and the Severn estuary. Stripe-winged Grasshopper is a brightly coloured species, usually green and brown with some degree of orange/red on the abdomen. The pronotal keels are gently incurved and there is a white line and stigma on the forewing. Both sexes are winged.|
|Slender Groundhopper Tetrix subulata|
|This is a common Groundhopper found at many sites. Seperation from Common Groundhopper is easy, with Slender Groundhopper having a much longer pronutum and wings of near equal length. The dry stony slopes of Warsop Main Pit Top has a large population and it seems fairly common around the Sherwood Forest area. There is considerable variation in both intensity of markings and colouration within this Groundhopper.|
|Common Groundhopper Tetrix undulata|
|This is a widespread species, yet can be elusive and easily missed when found with large numbers of Grasshopper nymphs. Seperation from Slender Groundhopper is easy, as the wings in this species are shorter than the pronutum, which itself is no longer than the abdomen. Usually can be found on most of Nottinghamshire's former pit tops, often in slightly damper locations than the Slender Groundhopper.|
