Last weekend I attended a workshop on Auchenorrhyncha hosted by Alan Stewart and Tristan Bantock, superbly organised by Mike Edwards of the British Entomological and Natural History Society (BENHS). More info about BENHS here and the Auchenorrhyncha Recording Scheme here.
Leafhoppers, planthoppers, froghoppers, treehoppers and cicadas are a sub-order of insects from the order Hemiptera that I know little about, despite the fact there are around 400 species in the UK. I’ve rarely seen or photographed any of them but I did get a photo of this red and black froghopper or ‘spittlebug’ Cercopis vulnerata earlier in the year at West Yatton Down. This should be an easy species for me to remember in future as it is our only red and black ‘spittlebug’ and our only ‘hopper in the family Cercopidae.
As a quick way of telling them apart, leafhoppers Cicadellidae have rows of spines on their rear legs (hind tibiae). Planthoppers Delphacidae have a large moveable thumb (spur) on their hind legs and froghoppers Cercopidae and Aphrophoridae have one or two stout spines on their rear legs.
We only have two treehoppers Membracidae and both have a backward extension of the pronotum (basically the back of the head is pointed like a spine). As for Cicadas, we only have one species, the New Forest Cicada Cicadetta montana which is very possibly extinct in Britain.
They are good indicators of site quality, particularly grassland, so I’ll be keeping a look out for them next year on Salisbury Plain.
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.
Polyommatus icarus – female
I’ve recently taken on the role of Entomology Sub-group leader for the Larkhill & Westdown Conservation Group. LWCG is one of three conservation groups that have access to some of the restricted areas of the Salisbury Plain Training Area (SPTA) which is where I took this photograph of a female Common Blue Polyommatus icarus resting on Devils-bit Scabious Succisa pratensis.
Leucospis gigas – female
Earlier this year I enjoyed a short break on the Greek island of Kefalonia. I took quite a few photos of insects, many of which I have still to identify. Needing help I uploaded this image of a wasp to the Hymenopterists Forum on Facebook. Almost immediately Irenel E. Popescu came back suggesting it might belong to the Leucospidae, a small specialised group of ectoparasitoid wasps within the Chalcidoidea superfamily.
Using this as a starting point, and after a further trawl of images on the internet, I concluded that it was most likely the Parasitoid Wasp Leucospis gigas.
