The truth about blackflies (02/29/05)

Stories. Our human curiosity draws us to stories. Used to be they were all spoken stories. These oral legends told us about our world, and our history. They were teaching stories, spoken to help us understand our past and how to live in the present to assure a secure future.

Now our stories are mostly written or presented on screen, and our curiosity is never sated. But how true are the stories we read, and the stories we see on the screen?

Did you ever play the "story circle" game? A dozen or more people sit in a circle, and the first one whispers something into the ear of the second. This person repeats the story to the third person, and so on around the circle. The last person speaks what he heard to the group.

More often than not, the story at the end is quite different than it was at the beginning.

How important is this to our understanding of the world? How does it change the ideas we have, and how we act on the information we gather?

In late March, I wrote a story about blackflies. I made the mistake of not checking my reference books before writing the story. I wrote some things as "facts" that were straight from my memory. And given that my memory isn't as good as it could be, this turned out to be a bad idea.

In describing how blackflies "bite," I stated, "they drop a bit of acid on you to eat away at the skin. Then they drink the blood that flows from the wound."
I remembered this from reading it somewhere. But now I can't find the source.

Instead, I found the "true" method blackflies use to get at our blood in Legacy, The Natural History of Ontario on page 154.

Blackflies feed by macerating the superficial tissues of the skin with an ingenious set of cutting and snipping mouth parts that operate like scissors.

The blades are equipped with backward pointing teeth to help prevent accidental dislodgment during feeding. The scissor-like action of the mouth parts causes a local hemorrhage, and the fly sucks up the blood. Hmm.

I'm sure I read somewhere that one of the biting flies uses an acid to burn a hole in our skin - but I can't find it anywhere. Maybe it was the stable flies?

Maybe that is why it hurts so much so fast when they land? I don't know. In any case, I told a story that wasn't true. I am very embarrassed. I
offer my sincere apologies.

As a nature writer, I believe it is very important to be accurate. We need to have true stories in order to understand the world we live in. We need
to have good references, and we need to check them frequently. And when a mistake is made, it needs to be corrected.

As well, people need to be aware that everything they hear, and everything they read is not necessarily true. When you have doubts, go to the source, and check the references.
