The Phasmid Study Group is a group for professional and amateur entomologists who are interested in the order Phasmatodea, i.e. stick and leaf insects, known as "phasmids", as well as other interested persons. Over 40 species of Phasmid have been named after members of the group.[ citation needed ] The group includes world experts in the study of phasmids worldwide.
The group was formed in 1980 and has since developed a worldwide membership. It has meetings twice a year at The Natural History Museum, London. It also distributes phasmids, free of charge, to its members.
The group has two publications. Phasmid Studies is issued occasionally and contains scientific papers and longer articles. The Phasmid Study Group's Newsletter is posted to each member twice a year, it contains shorter articles and announcements, and is printed in full colour with many photographs and much information on phasmids.

The Phasmatodea are an order of insects whose members are variously known as stick insects, stick-bugs, walking sticks, or bug sticks. They are generally referred to as phasmatodeans, phasmids, or ghost insects. Phasmids in the family Phylliidae are called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek φάσμα phasma, meaning an apparition or phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary lines of defence in the form of startle displays, spines or toxic secretions. Stick insects from the genera Phryganistria, Ctenomorpha, and Phobaeticus includes the world's longest insects.
The Society of Economic Geologists (SEG) is a scientific organization that promotes the study of geology as it relates to mining, mineral exploration, mineral resource classification and mineral extraction. The society's Publication Board publishes the scientific journal Economic Geology.

Cicadomorpha is an infraorder of the insect order Hemiptera which contains the cicadas, leafhoppers, treehoppers, and spittlebugs. There are approximately 35,000 described species worldwide. Distributed worldwide, all members of this group are plant-feeders, and many produce either audible sounds or substrate vibrations as a form of communication. The earliest fossils of cicadomorphs first appear during the Late Permian.

Megacrania batesii, commonly known as the peppermint stick insect, is an unusual species of stick insect found in northeastern Australia, the Bismarck Archipelago, the Solomon Islands, New Guinea, and possibly as far north as the Philippines. It is notable for its aposematic coloration, as well as its robust chemical defense mechanism. Its common name refers to the irritating fluid — with an odor resembling peppermint — that it sprays as a defensive action from a pair of glands located at its prothorax when threatened, as well as the cylindrical, twig-like shape of its body. A member of the subfamily Megacraniinae, it was first described by English naturalist and explorer Henry Walter Bates in 1865.

Peruphasma schultei is a species of stick insect found in the Cordillera del Condor region of northern Peru. In the wild the insect feeds on Schinus plants, but will feed on privet, Aucuba japonica and honeysuckle in captivity. In Peru they are only known to exist in a region of less than 5 hectares, but since their discovery they have become increasingly popular as pets worldwide due to their unusual colouration and they are now bred regularly in captivity.

The species has the Phasmid Study Group number PSG14.

The Concrete Society is a UK based non-profit company that was founded in 1966 in response to the increasing need for a single organisation embracing all those interested in concrete. On its formal inauguration, on 13 October 1966, the Society took over the work of the four organisations, by then in the process of dissolution, in order both to carry on their work and to extend it to cover the entire field of concrete technology and use.
