The Little Barrier Island Giant Weta (Deinacrida heteracantha) ( 
http://www.voyager.co.nz/~ianab/critters/weta1.jpg ) is just one of many
species of wingless orthopterans found throughout New Zealand.  There are
several families and over 100 species of these interesting insects.   Many
are rare or threatened; in recent years, increasing public interest in the
insects has resulted in protection measures such as breed-and-release
programs.  

Weta are characterized by their cricketlike morphology, winglessness and
very long antennae.  They are otherwise an extremely diverse group.
Though technically omnivorous, some are virtually carnivorous while others
are essentially vegetarian.  Weta inhabit a wide range of environments,
from caves to alpine rock outcrops and various temperate zones in between.
Many weta are solitary, but have a herd-like social structure with single
territorial male defending a group of females and young.  While generally
not aggressive, most weta are capable of inflicting a nasty bite if
mishandled.
