This book is the outcome of a lifetime's research by Warwick Don. He reveals that there are 37 established species of ants in New Zealand, 11 of which are considered to be endemic. This leaves 26 that are exotic or introduced, 2 of which are recent arrivals. Three of 4 additional recent arrivals pose serious threats to New Zealand's invertebrate fauna and economy if they ever become established.
