These are often seen around our garden in northern Thailand and I haven't been able to ID them yet. About 2.5cm long and a serious leaf eater by the look of it - any help would be appreciated. https://photos.smugmug.com/Macros-Close-Ups/i-SvDFc9L/0/038c1ac2/X5/_TG50030-Edit-X5.jpg Thanks in advance ...
