Introduction
The Hymenoptera, commonly known as ants, bees, wasps and sawflies, comprise a significant proportion of the insect diversity in most terrestrial habitats. This guide contains an interactive key to identify the hymenopteran families present in Australasia and provides information on their morphology, biology, classification and collection.

Morphology
Descriptions and annotated drawings of the morphological terms used throughout the guide and key.

Biology & ecology
Information on the diverse biology and ecology of the group, including parasitism, eusociality, herbivory, beneficial and invasive species and environmental monitoring and conservation.

Families
The families of Hymenoptera that occur in Australasia including images, biologies and defining characters.

Systematics
Current classification, phylogeny and number of described species of Australian and New Zealand Hymenoptera, including introduced taxa.

Collecting
A range of techniques useful for collecting Hymenoptera for taxonomic purposes and ecological studies.

Bibliography
A comprehensive source of published information referenced in the guide.

Summary description Minute to large spiders (1-15 mm), ecribellate, entelegyne, 3 claws, 8 eyes. Diagnosis Tarsus IV with a row of lightly curved, serrated bristles (Euryopis is an exception). Diagnostic characters used in the key In dorsal view check for the: colour of the legs; colour of the cephalothorax; colour of the abdomen. In lateral view check for the: shape of the cephalothorax; shape of the abdomen; presence of epigynum (in females) In ventral view check for the: shape and shading of the sternum; colour of the abdomen; presence epigynum (in females); shape and development of pedipalps (in males); presence of colulus among the spinnerets.
