Red and black froghopper

Cercopis vulnerata

Cercopis vulnerata

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.

  1. Nice shot, well-composed. I didn’t know that about the differentiating spines on the hind legs…probably a better way to tell them apart than guessing by the shapes of their heads!
