In his book, "A Naturalist in Borneo", Shelford includes several references to phasmids (pages 147-155, 215, & 315). Shelford's observations of Bornean insects are based on both observation in the wild, and in captivity. He comments on the nocturnal habits of many phasmids, and refers to his observations on "some that I have kept in captivity". He then goes on to say that "Most of the winged species of Phasmidae, especially some with brightly coloured wings, are diurnal feeders, or at any rate feed as readily during the day when in captivity as during the night". He makes several observations about eggs of phasmids in Borneo, and also reveals that he was keeping in England "a small colony of an "Indian Stick-Insect that has bred parthenogenetically for several generations" at the time he was writing his book.
