Phasmid Study Group (PSG)

Phasmid Study Group (PSG) The Phasmid Study Group (PSG) is a worldwide organisation dedicated to the study and captive rearing of stick insects and leaf insects ("phasmids").

Since its formation early in 1980, the PSG has expanded to more than 350 members in over 30 countries including people of all ages and ranging from beginners to professional entomologists. The purpose of the group is to encourage studies of all aspects of Phasmids (stick- and leaf- insects). More information about the group, including how to join and details of the PSG publications can be found on the PSG website (below).

We had a great winter meeting and AGM yesterday at the Natural History Museum despite some IT challenges.

A really good turnout, some truly fascinating talks and a very lively livestock exchange - with some young enthusiasts going home loaded down with loads of interesting species.

For anyone who missed the event or had problems joining remotely, here’s a link to a paper by David Labonte and team on insect locomotion.

I’ll add a direct link in comments to a video of the brilliant treadmill they’ve created to capture the rather unpredictable movements of phasmids.

Insect Locomotion Movement is an essential aspect of animal life, and insects are no exception: they run, climb, carry loads, jump, fly or strike – all by fine-tuning the neuromechanical control of limbs and their interaction with the environment. We aim to understand the diversity of locomotor pa...

The AES Exhibition and Trade Fair is the oldest of its kind and a firm favourite with entomologists of all levels and ages.

Bookings are flooding in as usual from traders of books, equipment, livestock and specimens so we'd encourage any latecomers to book now while there's still space.

We'd really like to encourage adults, children, groups and schools to come along too and share their enthusiasm, observations, photos and work with others - we'll even have prizes for the best exhibits.

Snap the QR code below for more information and booking forms - and share this post with anyone you think might be interested.
