Hymenoptera. In Australia the Hymenoptera are parasitized only by a few 

 members of the subfamily Goniinae. The Anacamptomyiini are parasites in the 

 nests of certain Vespoidea, and several species of the Froggattimyia-Zenargomyia 

 complex (Blondeliini) attack the larvae of certain sawflies (Pergidae and Argidae). 



Phasmatodea. Although 130 species of Phasmatidae are known in Australia 

 only two of these are known to be hosts of Tachinidae. These two species are 

 attacked by an undescribed species of Tachinidae that represents an undescribed 

 genus of doubtful affinity (but possibly belonging near the Acemyini). This 

 tachinid is remarkable for its very strong downcurved hook-like ovipositor. The 

 hosts of the genus Mycteromyiella (? Ethillini) are not known in Australia, but 

 in the Solomon Islands species of Mycteromyiella attack stick-insects of the genera 

 Ophicrania Kaup and Megacrania Kaup; it seems likely that the Australian species 

 of Mycteromyiella might similarly attack phasmatids. 



Mantodea. Only one of the 118 species of Mantodea in Australia has so far 

 been recorded as host of a tachinid, viz. Pseudomantis alboftmbriata which has 

 been found parasitized by Exorista cor as. Ordinarily the Lepidoptera are hosts 

 of exoristine tachinids, but the record of E. coras from a mantid and of an 

 unidentified Exorista species from a mantid in Guadalcanal (latter obtained by 

 R. W. Paine) suggest that parasitism of mantids by exoristine tachinids is an 

 occasional phenomenon in a group that habitually parasitizes lepidopterous 

 caterpillars. In other regions the Mantodea are parasitized by other tachinid 

 tribes that are probably close relatives of the Exoristini, such as the Masiphyini 

 in the Neotropical Region and certain Ethillini in the Ethiopian Region. 



Diptera. The only record of Diptera as hosts of Tachinidae in Australia is that 

 of Spratt & Wolf (1972). 



The subfamilies and tribes of Australian Tachinidae and their host groups 



The following synopsis is given to show at a glance the various host groups for 

 the subfamilies and tribes of Tachinidae known to be represented in Australia. 

 The subfamilies and tribes are listed in the systematic order adopted in the 

 taxonomic catalogue (Part II). For some tribes there are no Australian host 

 records yet available, in which case the host information given is derived from 

 extra-Australian records and annotated as appropriate.
