Periphetes graniferum "Samar"
Samar, one of the larger islands of the Philippines. The island lies on the east side of the centrally located archipelago of Visayas, just northeast of the island of Leyte.
Bramble (Rubus fruticosus), Pyracantha (firethorn, info Philippe van der Schoor), hazelnut (Corylus sp.)
Adult length -
Male about 7.5 cm, female about 8.5 to maximum 9 cm.
Sufficiently spacious, little ventilation is best (more info with breeding experience). Ideal temperature is higher than room temperature, preferably around 25 degrees.
Incubation time eggs -
4 to 6 months.
Experience with this species -
The nymphs hatch easily and numerous, as long as the eggs are regularly moistened and are reasonably warm. After 4 months the first nymphs already appear. The nymphs are very thin and light brown in colour, they also have the typical posture that all Periphetes have. In the event of disruption, they quickly run away or fall. At temperatures higher than room temperature males will already be adult after 3 months, females will take a few weeks longer (3.5-4 months). In the sub-adult stage, both sexes already show their colour splendour. The females are beautifully yellow / orange on the belly side, and to the head and rear they become beautiful green with a bright shine. The males already show the bright orange on their backs and the legs already turn blue. Then, after the last moult, their true beauty emerges. Especially the males are very unmanageable. Picking them up can be quite frustrating, they really do EVERYTHING to escape your grasp: jumping away, walking backwards, wringing, jiggling, dropping, hysterical behaviour ...
When the first nymphs came out, I kept them in a double-ventilated terrarium, but after a few victims, I placed the animals in a residence with only one ventilation strip at the top and only kept the paper on the bottom very moist (even wet). The nymphs were mainly fed with bramble and firethorn. No nymphs died after this transfer. From this I conclude that the best method is to keep them barely ventilated, very humid and sufficiently warm. I have never been able to observe any problems due to too dry air under these circumstances. The females really lay a lot of small, almost round, beige to brown eggs. Not the easiest kind but certainly worth the effort. Their colour splendour and the fact that they are very active both during the day and at night, makes this a very interesting phasmid species to culture.
