Here is a phasmid resource, Care sheet (Medauroidea extradentata), courtesy of Chris Pull:

PSG5 Medauroidea extradentata

Common name: Vietnamese S/I

Subfamily: Phasmatinae

Origin: Vietnam

Adult size: Females: 110mm Males: 75mm

Food plants: Bramble, Hawthorne, Oak and Rose

Description: Basically a brown stick-like insect that appears to have two demonic horns on it’s head. Long slender legs and a few short spines here and there. They vary in shades of light brown to a rarer green.

Comment: Wow, it’s been a very long time since I kept these. In fact, they were the first phasmid I kept. Keep them relatively dry, but spray about once or twice a week. Keep at room temperature and they should do fine. A very easy insects to culture!

Thanks Chris!
