These mantis go by different names Malaysian Ghost Mantis, the english common name is The Bark Horned Mantis.
Due to there rarity in the UK, gauging temperature and humidity has been a challenge, Currently they are kept at 26-28c and 80+% Humidity as nymphs, suiting a bioactive approach to their enclosure.
As they get older I would lessen the humidity as the adults do not seem to require as much.
