It’s been awhile since Tuesday Tunes featured a song about those beautiful bi-winged bugs the flies, so I think we’ll rectify that!

This isn’t the first time that Wire has been featured here on Biodiversity in Focus, with their song Outdoor Miner previously making the list. That song featured a relatively accurate depiction of a leaf miner fly, probably in the family Agromyzidae. Today’s song features flies a little closer to home, repeatedly talking about a fly in the ointment and flies causing more disease than fleas.Well, that and a divergent wasp dealing with plate-glass (side note: Flickr is fun).

So what might the flies be? Well I’m going to go with the common house fly (Musca domestica) for the fly in the ointment, just based on ubiquity and the odds of one ending up in someone’s moisturizer/tonic/soup. How about the flies causing more disease than fleas? Well, fleas are vectors for a number of diseases, with the big one being the Bubonic Plague. With an estimated 75 million people killed during the Black Death pandemic and another 12-15 million more killed in epi- and pandemics up until the mid 20th century, I think we can confidently put a back-of-the-napkin (BOTN) estimate of 100 million deaths attributable to fleas in recorded history. Tsetse flies (Glossinidae, 23 species total, 2 of which are of medical importance to humans) are vectors for the trypanosome that causes African Sleeping Sickness, which was listed as killing 48,000 people in 2008. A BOTN gives me an estimate of 100 million deaths in the last 2000 (50k x 2000 years, assuming smaller populations but higher mortality rates), so Tsetse flies are a possibility. Our next suspect might be the common house fly from earlier. Known to spread diseases such as typhoid (BOTN = 20 million deaths out of 450 million in past 2000 yrs), cholera (BOTN = 30 million deaths out of ~600 million in past 2000 yrs), and dysentery (BOTN = 50 million deaths out of 1.5 billion in past 200 yrs) among others, the house fly may be a dark horse in this race.

Of course, the best bet are the mosquitoes. With the genus Anopheles (the vector for Malaria) responsible for easily 100 million deaths in the past 200 years, not to mention the deaths attributable to Yellow Fever & Dengue Fever (Aedes aegypti) and “minor” diseases like West Nile Virus and Japanese Encephalitis (Culex). I think it’s pretty safe to say that mosquitoes are the most deadly insect known to man!

Anyways, that was a pretty morbid tangent from the song, so let’s just listen to some music shall we?

(All estimates based on conservative values found in Wikipedia. Some estimates may be horribly off, so best to do a more thorough literature check if you need more reliable numbers!)
