I have a feeder in my cham's viv that is small, not the best so occasionally a silkworm will escape it. So yesterday I noticed a silkie eating a leaf the Ficus tree. So by the time I found my phone to take the picture, the worm was gone! I haven't seen any other leaves that look like they were eaten but I did throw out the worm that was (now) at the bottom. Is this likely to happen or was I just seeing things?
