It was a dark and stormy night. Or rather, the night darkness concealed the source of the intense storms. That seems much better. My wife and I waited for the storm to pass that evening before setting off to walk the dogs. The reflection of the street lights glistened off the wet streets.
All down the street, I could see small ridges. Upon closer examination, I could see that there were literally hundreds of night crawlers stretched out perpendicular to the road. The road friction made them stretch out to a tortured length of about a foot and a half. Normally plump, this condition thinned them out considerably. Night crawlers are earth worms on steroids.
Feeling some form of compassion for this Lumbricus terrestris, I started to scoop them up and toss them back on to the grass. Some worms can survive being cut in half but being half squashed flat by a truck did not seem very survivable to me.
Now, under normal conditions worms produce a fair bit of mucus. Adding torrential rains to that seems to add to mucus production as the worm exodus continued. I started to regret my misplaced compassion and tried to distance myself from my emotions. My wife just simply distanced herself.
I assumed the common knowledge that during intense rain storms worms attempt to escape drowning in their burrows. However, they breathe through their skin which needs moisture. So there may be a number of other reasons why they engage in such risky behavior of stretching themselves out on a busy road.
One good reason would be migration. Lots of rain would allow them to move great distances. However, half of them moved from the south to the north, while the other half moved from north to south. But, hey, they’re worms. The grass always seem more organic filled on the other side of the street it is said.
An interesting phenomena occurs when you experience a situation and learn some new facts about it later. I learned that another good reason worms travel is that they want sex. My recollection of the event now includes an added ‘ewww’ quality to it. And what better time to find a mate than when everyone else is stretched out in the same area. We have a beach here that seems to serve the same purpose for humans.
Although worms are hermaphrodite, male and females together, they cannot reproduce solely by themselves. They need a mate. I must have cast aside, and severely disappointed, several dozen night crawlers. Destined now to remain virgins they’re probably bitter. Unless that was going to be their choice anyway, and so that is perfectly ok.
This sex migration behavior can bring down planes. After a rain, worms like to stretch out wherever they can, including airport runways. Worms do not get sucked into turbines, but the birds coming to eat the worms can be. Particularly the flocking birds like gulls which tend to ignore whatever happens around them when they fight over food. So airport authorities tend to use fungicides to reduce worm populations.
Night crawlers contribute to the US current account deficit! Some politician should complain about this. If nothing more than the neat optics it provides. “Congress needs night crawler NAFTA negotiations!” Apparently $20 million of night crawlers are exported to the US each year with little or no USA content. A few years ago, the price leapt from $35 per thousand worms to $80 per thousand. Economics 101. Supply was tight, and owing to inelasticity of demand, prices skyrocketed. Worm futures may not have the panache of Tesla stock, but you would have made a fortune otherwise.
