Paracalliphora atjgur. 



Froggatt (1915, p. 19) reported breeding the species from 

 carrion all the year round though it was during winter that it 

 infested sheep. He recorded that during winter the larvae 

 required 2 to 3 weeks to become fuUy fed while the pupal 

 stage occupied a month to 6 weeks, so that from 6 weeks to 

 2 months were required under laboratory conditions, but that 

 a fortnight or even a month longer was necessary under natural 

 conditions. During summer, he stated, only 14 days intervene 

 between the egg and the emergence of the adult fly, larvae 

 being fully fed on the seventh day. 



In an earlier paper (1913a, p. 23) he mentioned that eggs 

 laid in November gave rise to larvae which pupated in 6 days 

 and emerged 11 days later, the period from the egg to 

 emergence of the fly being 14 to 15 days (his dates show a 

 period of 17 days). During December, 18 days elapsed in a 

 case jecorded. 



Calliphora erythrocephala Meigen. 

 This large, dark blowfly, an importation from Europe, 

 is common in New Zealand and in Sydney. As we have seen 

 only one specimen in Brisbane it must be very rare, though it 

 may succeed in estabhshing itself. No data regarding its 

 biology in Australia have been published. 



Bishopp (1915, p. 327) mentioned that in Eastern Texas 

 the incubation period was 24 hours ; the larval feeding stage 

 3 or 4 days ; the. pupal stage 7 to 9 days ; the period from
