This must be one of the most magnificent phasmids in culture. The males, on the other hand, are simply brown and grey, much smaller and much slimmer than the females. There are quite a few problems known in connection with the hatching of the nymphs. Common problems are: nymphs remain stuck halfway during hatching, or the eggs do not hatch at all. Nymphs are relatively large for the small eggs from which they emerge. They are bright green, and about 1.5 to 2 cm in size, and in my opinion pretty thick. Once they have emerged from the eggs, everything goes automatically, they easily start feeding, grow like weeds and when everything goes well, they are fully grown after 4 or 5 months. The eggs are glued and put in nice straight rows, preferably on the walls of the enclosure, on leaves of food plants, or on branches. You can loosen the eggs by first spraying them a little, soaking them for a while and then carefully removing them with a brush or a piece of paper. My opinion is that it is best to leave the eggs where the female has glued them. There is a reason that she has chosen that spot (temperature, light, moisture and other factors may be just right in that place). It is not yet certain whether the food plants that we give them are good for them, but for the moment there are no other plants that are accepted.
This summer I experimented with American bird cherry and they seemed to like it very much, they ate as much of it as the laurel cherry, which was also offered, so they did have the choice. During the day these animals are usually hidden at the bottom of a leaf, and they only become active in complete darkness. Be extra careful when changing the food plants: they are fast! Several times I had to catch escaped individuals. They are so fast that you can barely follow them with your eyes. Finally, it is very important to keep this species very in a very damp enclosure, the windows may certainly be fogged. The conditions of other breeders, who did not succeed in breeding these animals, had one thing in common, the enclosures were very well ventilated.
