Hymenoptera. In Australia the Hymenoptera are parasitized only by a few 
members of the subfamily Goniinae. The Anacamptomylini 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 Mycteromyrella (? 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 albofimbriata which has 
been found parasitized by Exorista coras. Ordinarily the Lepidoptera are hosts 
of exoristine tachinids, but the record of EF. covas 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.
