Lessons from a Tiny Teacher

by Carl Strang

A moment came Saturday night when I had an experience which seldom happens anymore. I was walking to my car to head home from Mayslake Forest Preserve after watching First Folio Theater’s excellent performance of Shakespeare’s The Merry Wives of Windsor on the outdoor stage. I heard a singing insect that I did not recognize.

This was at the end of a day that had been fairly productive. I had found green-winged cicadas in two additional counties in the afternoon. During the play’s intermission I heard the first sword-bearing coneheads of the year in Mayslake’s prairies. I also heard the first unambiguous fall field crickets of the season.

But then, as I headed for the car, I heard a trill that seemed unfamiliar. At first I thought it was probably something I was hearing for the first time this season, and its identity would click if I just listened for a short time. While waiting for that click to happen I went through the mental checklist. It was a high-pitched, musical trill. So, it had to be a cricket. I approached it, and the hidden insect kept singing until I was beneath it. So, it had to be a tree cricket. I looked up into the spruce above me, but without a flashlight there wasn’t even a small possibility of seeing it. The checklist continued. All the early arboreal tree crickets have pauses in their trills, at least little ones. Therefore it wasn’t a two-spotted, or a Davis’s, and certainly not a snowy. I knew I would be there at night in a little over a week, and resolved to make a recording then. It wasn’t until later that the obvious solution filtered through the late night fatigue. It had to be a pine tree cricket. I realized that I had allowed myself to think of Oecanthus pini as a late-season species, but that was because Nancy Collins introduced me to pine tree crickets in September last year. I had noted that they were going strong at that point, and so could not say when they had begun. Everything fit. It was a continuous musical trill, but not as loud as tree crickets usually are. It was in a conifer. The Singing Insects of North America website gives starting dates consistent with the end of July at this latitude.

The lessons were several: be open to all sounds, notice them all; pursue incongruities if a song isn’t a clear match with past experience; abandon assumptions that are constructed from limited past experience. That’s a lot of profit gained from one tiny cricket, and I am grateful.

    I’m still waiting to hear singing by any tree crickets up in in SE Wisconsin.

    Wonderful post, Carl! By the way, Pine Tree Crickets are the first tree crickets to sing here in NE Ohio, I heard them in a stand of tall pines on Friday evening. it was a delight to hear some tree crickets after all these months.
