The Phasmid Study Group

The Phasmid Study Group (PSG)

The Phasmid Study Group is the society for anyone with an interest in Stick and Leaf insects, however amateur or professional you may be, you will be welcome. The pupose of the group is to encourage studies of all aspects of PHASMIDS (Stick and Leaf Insects).

Since its formation early in 1980, The Phasmid Study Group has expanded to more than 500 members in 23 countries, including people of all ages ranging from beginners to professional entomologists. Since Phasmids have recieved little attention until recently there is considerable scope for the amateur to contribute valuable information.

The PSG now have their own web site and for the most up to date information, particularly for details pertaining to membership you should visit The PSG Home Page
