Black Flies Don’t Bite They Suck
Hat tip to The Adventurist.
A friend of mine used to do a lot of work as a graphic artist and much of his work appeared on T-Shirts sold in Maine and then abroad as their popularity grew. Several of his designs became very popular and I believe it was him that used the “Maine State Bird” on a T-Shirt. The one I do remember vividly is “Black Flies Don’t Bite They Suck”.
Evidently there are bad things that come with the good when it comes to cleaning up our rivers and streams - black flies. It appears these 2,000-plus species of blood sucking insects are finicky when it comes to where the female fly decides to drop her eggs that have been nourished with your blood.
Many people believe these bugs thrive in standing, stagnant and even murky, dirty water. That actually closely describes where mosquitoes breed but black flies prefer pristine, fast-moving water.
Many of Maine’s rivers used to be very dirty, polluted from paper mills and municipal runoff which included raw sewerage. Over the past 30 years, we have made great strides in cleaning up our waters and as a result we now are seeing more abundant black flies and the pesky creatures are showing up in places many of us never saw them before.
I grew up on one of America’s ten dirtiest rivers, the Androscoggin. Not so now. The area where I now spend my summers, the Upper Androscoggin, is a decent place to go fishing for rainbow, brown and brook trout, as well as bass. The state record rainbow was caught on this river near here.
Of course as we watched the river clear up, stop stinking and become a bit more user friendly, we also witnessed more and more fish, birds and other wildlife. According to an article yesterday in the Boston Globe, much of the return of the fish and wildlife is also due to the return of the black fly.
Unlike mosquitoes, which breed in stagnant pools, black flies like clear running water. The adult female typically mates with males in midair before seeking a blood meal to nourish eggs. The female then deposits the eggs in flowing water, where they hatch into larvae. But the running water must be nearly pristine: Black flies are incredibly sensitive to pollution.
This helps explain what happens when hardcore fishermen venture deep into prime wild brook trout territory only to emerge a quart or two low on blood and demand a very large and raw beef steak. Brook trout and black flies seem to make a good combination as far as survivability goes. Both like clear and cold water, so when you find prime trout fishing you also are apt to find prime blood sucking by black flies. This helps ensure the survivability of the brook trout as whimpy casters dare not venture into these areas.
According to the same article in the Globe, Maine has no intentions of doing anything to slow down or stop the growth of the black fly. They are still enjoying the successes of cleaning up their waters and aren’t much interested in dumping things back into them in order to kill black flies. Pennsylvania, it’s reported, spends $6 million annually to rid the state of the pesky suckers.
I guess then it would be prudent to inform readers that the next time you are swatting and batting at nasty biting black flies, itching and scratching until your skin falls off, think about how clean your water must be and the great job we have done getting to a point where we all must suffer from the results.
Yippee!
