Aglia tau or the Tau Emperor is one of the three species of Saturniidae that can be found in Belgium. They are not difficult to breed as long as you give them enough space. In all stages caterpillars dislike company. Overcrowding is the fastest way to kill them all. As long as you keep this in mind you will have no problem seeing caterpillars develop. They start as a strange creature with long spikes on their front section. With each shedding of the skin these spikes become shorter and shorter, making the animals less and less interesting to look at. Nothing would suspect that the green, inconspicuous adult caterpillars will next spring turn into one of Europe's most attractive moths.
