Abstract - A review is made of significant literature relating to Zelotypia stacyi Scott since the first record of its discovery, and additional information added. Collecting data indicate that more than half of the specimens were taken in March, and most of the remainder in April. Occasional specimens were collected in December, January and May. Eggs are scattered indiscriminately. Larvae bore into eucalypt branches, where, later on, larvae and pupae are able to move vertically in tunnels in the trunk. Pupation occurs behind a plug of material which is pushed outwards before the emergence of the adult. V. J. Robinson found that the combined larval and pupal period occupied a minimum of four years. Eucalyptus tereticornis is the major host plant, although E. grandis, E, punctata, E. resinifera, E. saligna and the hybrid E. saligna - E. botryoides have been mentioned. Once regarded as restricted to N.S.W., recent data confirm older records of its occurrence in southern Queensland. Natural enemies include the fungus Cordyceps sp. and a species of black cockatoo. The pyralid moth Tirathaba sp. is also associated with Z. stacyi.
