Please can you identify this creature

Hi, please could you help us identify this creature which my brother snapped in his little corner of the jungle near Cayenne, French Guyana – it is obviously hanging on a tree in the photo, is well camouflaged and looks pretty scary – he has never seen anything like it before, despite living there for about 5 years. Is it poisonous or dangerous (should he be worried??!)

Hi Frankie,
This is a harmless female Katydid.  What appears to be a dangerous stinger is really an ovipositor.  We thought this might be a Moss Mimic Katydid like one from Costa Rica that  Katydid expert Piotr Naskrecki identified for us in the past.  When we wrote to Piotr, here was his response:  “Hi Daniel,  Very hard to say from these photos. It looks more like Acanthodis than Haemodiasma (which does not occur in Fr. Guiana.)  Piotr”
