Fly on a Rose Petal

Apr 16, 2009

Poet Gertrude Stein wrote in her 1913 poem, "Sacred Emily," that  "a rose is a rose is a rose."

Things are what they are. The laws of identity. No matter where I go, there I am.

When I captured this photo last Sunday of a fly on a rose petal, I immediately thought "A fly is a fly is a fly."

Not to an entomologist.

The common house fly (Musca domestica Linnaeus) commonly breeds in manure, compost piles and dumpsters.

The housefly is known to transfer at least 100 different pathogens, and carry about 6.6 million  bacteria on its body at a single time, according to UC Davis forensic entomologist and fly expert Robert Kimsey.  It's responsible for transmitting both parasitic and bacterial pathogens as well as viruses. Among them: typhoid, cholera and dysentery (bacterial diseases) and infective hepatitis (virus).

It's enough to make you "stop and fell the roses."
