Report Disease/pest on Myrmecodia beccari in Diseases and other problems Posted August 2, 2020 On 7/28/2020 at 2:56 PM, Anita said: Hi everybody, I purchased Myrmecodia beccari a few weeks ago and it came with something weird on the undersides of her leaves. I don't know whether it's a disease of some sort or pest. It is not critical yet but I think more and more leaves are getting it. I cut those leaves off just in case. I would appreciate it if you could give me any kind of information. Could be Thripses? Anyways, I am new to ant plants, bought same plant recently, it does have similar brown spots under the leaves, can't see any insects there though.
