There has not been much activity in my millipede (Luculus terrestris) tank recently, the animal did not come out at night to feed, nor did it produce any waste. I was starting to get a bit worried, but I eventually discovered that it was hidden under the big mossy pillow that I brought from my trip last year and has given itself to shedding its old exoskeleton.
Last time some of my millipedes moulted was in July 2012. Now I only keep one, so I cannot tell whether it is the one that has already moulted or not, but I would say it is a different one. Here are some pieces of the old exoskeleton of which I managed to take photos back then.
