以上是PM內容一 Hi Randolph, I am pretty certain they are from Taiwan but they are Polyphagids not Blaberids (Pycnoscelus, Opisthoplatia and Rhabdoblatta are very different= Blaberids). I saw that really neat roach photo you put up. Is that a polyphagid? It looks like one but that doesn't necessarily mean it is. Probably you can find females and nymphs under ground in piles of leaf litter in the areas you find the males. Thanks, Orin

only Opistoplatia orientalis and nymphs of Rhabdoblatta spp don't have wings but bigger than 20-25 mm, but O.orientalis has yellow sideline and Rhabdoblatta spp have wings
my biggest doubt is: are u sure they are from Taiwan?
