Green Bean stick insects are native to the Caribbean including the islands of Grenada, St Vincent and Guadeloupe.

Both males and females have vestigial wings. This means that their evolutionary ancestors had wings and were capable of flight. However, the ability to fly became less useful and so their wings diminished over many generations until they became small and no longer worked.

Males are small and brown whereas females are large and green.

They feed on a variety of tree leaves native to the Caribbean but will happily eat bramble, eucalyptus and oak in the UK. *
