There are 30,00 types of flies, one of the most familiar and widely distributed is the house fly. Besides being annoying it can also carry diseases like typhus, dysentery, and tuberculosis,.
The introduction of cattle to Australia in 1788 gave the fly increased access to one of it’s food sources, animal dung.
Australian have battled flies in the home and in the paddocks.and the Museum holds a wide variety of approaches to combat flies from poisons like the oddly named and decorated Daisy killer pictured above to fly swats, fly paper and glass fly traps.
The Daisy killer metal tin has five holes in it which have felt wicks and it contain arsenic.
When the tin is filled with water and the corks replaced and thoroughly shaken (while kept level) the fly poison mixes with water and is absorbed through the wicks which become moist and sweet . The flies are attracted by the moisture and sweetness.
The tin is oddly pretty for a poison container which perhaps explains why a 1910 newspaper article describes a young child being attracted to the container and licking it, with fatal consequences.
There has been a great variety of poisons and pesticides used to combat the fly with products named ‘Must Die’ and ‘GOT- U ‘ and Anti buzz buzz’ and ‘Aussie catchy foot’ fly papers.
The best known advertisement known to generations of Australians was the Louis the fly campaign which started in 1957, he now has his own Facebook page.
The ‘Flies have dirty feet’ poster is one of a collection of 17 Australian health and safety posters that have survived from the 1950s. In their range they cover many of the public health issues that concerned government authorities at that time. One of these issues was cleanliness.
The mid-20th century was a time when personal and civic cleanliness was stressed as a means of combating disease, both because dirt itself harboured germs and because filth and litter attracted vermin – such as rats and flies – that were branded as disease-carriers.

The viceroy butterfly appears similar in color and pattern, but is markedly smaller and has an extra black stripe across the hind wing.
The eastern North American monarch population is notable for its annual southward late-summer/autumn migration from the United States and southern Canada to Mexico.
During the fall migration, it covers thousands of miles, with a corresponding multi-generational return North.
The western North American population of monarchs west of the Rocky Mountains most often migrate to sites in California but have been found in overwintering Mexico sites Monarchs were transported to the International Space Station and were bred there.
EUROPEAN BEEWOLVES: wasps that preys on bees, harbor symbiotic Streptomyces bacteria in specialized antennal reservoirs.
The bacteria are secreted into the wasps’ lair, later taken up by the wasp larva and applied to the larval cocoon where they produce antibiotics to protect the wasp offspring against pathogenic fungi.
Beneficial partnerships between microbes and animals like the European beewolf have inspired a rich body of research into the bioactive products of host-microbe interactions, which could have purpose in medicine and disease prevention.
