Ironically I live very near the site in Sussex that these were first discovered in I believe 2006, and have never seen one. Recently I got back from a trip to Kent and posted these two photos (links below) hoping for an ID on this odd speckled cricket. As it turns out a very buggy friend ID'd them as Sickle-bearing Bush-cricket nymphs.
I have two questions, I've contacted the nature site we saw them at and am awaiting information on any previous sightings, but I'd like to know if/where I can find any information on distribution within the UK (as the NBN Gateway has none).
I'd also like confirmation on the ID if possible, before I make a report on the Orthoptera Recording Scheme site.
