Speckled

Speckled Bush-cricket, Leptophyes punctatissima, female

Leptophyes punctatissima – female

This is probably our commonest bush-cricket, the Speckled Bush-cricket Leptophyes punctatissima is a small green cricket with a brown stripe down its back (admittedly it’s not very prominent on this particular specimen) and is covered in tiny black speckles. Crickets are easily distinguished from grasshoppers by their long antennae which can be easily twice as long as the body. In comparison grasshoppers have rather short antennae.

Roesel’s Bush-cricket

Roesel's Bush-cricket, Metrioptera roeselii, male

Metrioptera roeselii – male

Taking macro photos of insects is as much about luck as anything. But of course you increase your luck by being out there. I was laying on Morgans Hill trying to take a photograph of a grasshopper when this little lady crawled out of the grass allowing me to get this side-on shot. It’s a female Roesel’s Bush-cricket Metrioptera roeselii. You can tell it is a female by the scythe-like ovipositor and that it is Roesel’s by the yellow/green edge to the pronotum and the three spots/patches just behind on the abdomen.

Roesel’s are normally brown or yellow-brown with a hint of green and maybe a touch of red but this may be the rarer green form.

This is a cricket that was rare in Britain prior to the 20th Century and pretty much only found on the South-East coast of England. Since then it has rapidly increased its range in the South, to the North and West possibly helped by the rough grassland found along the sides of many of our roads which have provided it with ‘corridors’ inland.

It favours damp grassland that is relatively undisturbed. The male’s high pitched stridulation is meant to sound like the crackle of overhead electricity cables. Have a listen here thanks to http://www.orthoptera.org.uk

It’s also said to be reminiscent of the song of the Savi’s warbler. You can listen to that here thanks to http://www.rspb.org

Dark Bush Cricket

Dark Bush Cricket – Pholidoptera griseoaptera – Female

Pholidoptera griseoaptera – Female

On Saturday I attended a course on Grasshoppers, Crickets and Allied Insects. Allied insects covers groundhoppers, our native cockroaches and the earwigs. So what did I learn? In the UK there appear to be eleven grasshoppers, about fourteen crickets, four true crickets and three groundhoppers, all of which can be identified in the field or from photographs and then keyed out. So for once there isn’t really any need to collect specimens, particularly as most will lose their colour after death anyway. Three of the crickets, the Field Cricket, the Mole Cricket and the fabulously named Wartbiter are protected under the 1981 Wildlife and Countryside Act and so cannot even be handled without a licence from Natural England. Apparently even taking photographs of them is discouraged as this could be interpreted as interference.
