We are in Australia and have hundreds of phasmid eggs that are just starting to hatch. The adults ate gum leaves, but I know the babies need the tips of new gum leaves. These aren't easy to access and the baby phasmids are dying. Is there anything else we can feed them, because I'm having trouble getting to the younger leaves of our gum tree supply! Advice from anyone in Australia in particular with baby phasmids greatly appreciated.

Share anything you would consider to be a paranormal experience. I am also interested in sightings of cryptids which in a sense can be considered pretty paranormal. Any experiences with O.B.E or astral projection. Maybe someone believes in curses or pychic powers and has had some experience with those. I am also interested in hearing about your experiences with ouija boards and possible demonic entities either derived from the ouija or elsewhere. Share you true stories of yourself friends and family.
