Australia,
especially in summer, is known for its wide variety of insects, particularly
flies. However, record heat and spring rains have enabled insects, especially flies and mosquitoes, to flourish
(Sydney Morning Herald, January 10-11, 2015).
There are two
main species of flies in Australia: the housefly (Musca domestica) and the bush fly (Musca vetustissima) – commonly called the blowfly. Many Australians
would say that there is a third main species: the barfly (a person who drinks alcohol in a bar)!
House flies are
attracted to food and are usually found indoors. Bush flies, found outdoors,
are attracted to sweat (animals and humans) and meat juices. Forensic
entymologist and associate professor James Wallman of the School of Biological
Sciences at the University of Wollongong says that female bush flies drink
sweat to ensure the growth of her eggs. Hence bush flies need the moisture in
sweat.
Mosquitoes are
also on the increase due to the hot weather. They also like water, which is
ideal for breeding. Therefore the heavy spring rains in Sydney have resulted in
significantly increased mosquito numbers.
