Final, final update, November 4, 2022:
Last ? Snowy Tree Cricket singing in Perrysburg, Ohio. Not expecting any more days with temperatures in the 70’s, I certainly was NOT expecting any temps of 70° at 7 PM. ( The past week of those daytime temps. did not produce warm temps after dark.)
So I drove to check out places I last heard True Katydids and Snowy Tree Crickets. Low and behold perhaps the same one singing in tree line as last week, on Keller Road at 7:55 PM singing at 66°, on my car thermometer, 69° on my phone for Rossford, Ohio. Home thermometer showed 65° when I left.
Final update on 2022 chirper season: November 2, 2022.
I have been living in this area for eight years and I have been following three populations of Snowy Tree Crickets. The final 2022 update.
We had another 70°F day. I made sure I stopped by Keller Road to see if the Snowy Tree Cricket I heard last week. I heard only some ground crickets as pretty much all the leaves were gone.
And at our Lot 176 “my” Snowy wasn’t singing as most leaves in the area he was last heard are gone. I had about a half dozen Jumping Bush Crickets singing and a ground cricket across the creek.
The last place I have been checking is the population in the line of crab apple trees at Friendly Village’s entrance Boulevard. No leaves equals no tree crickets despite the temperatures at 7 PM was 64°F.
At the place I walk the dogs there is a small shrubby area that today had a different species of tree crickets and a dozen ground crickets singing. Below is a recording of them.
This is my records of the past three years first day they were heard and last day.
Today’s Nature Note, October 30, 2022:
Having cooler temperatures for several weeks, I thought it was the last time I would hear my two favorite chirpers this year: True Katydids and Snowy Tree Crickets. So much to my surprise after several days of 70°F , they both were singing. The Snowy in my yard during the day and a couple True Katydids singing after dark at a local population. Below are two videos of them singing.
October 22, 2022 a Snowy Tree Cricket sang for several nights after two weeks of colder temps that prevent them from singing after dark. Several days of temperatures in the 70’s allowed them (elsewhere) and the one at my house sing. Being the last one, he is probably desperate. He sang for about two hours into the dark and one night it was still singing at 2AM when it was still 60°F.
The Snowy Tree Cricket (see photo below courtesy of the website “Songs of Insects”, stops singing between 60 and 65 degrees F. But other species, like the Fall Field Crickets, most of the local ground crickets and the Jumping Bush Cricket all sing below 60°F and I have heard them singing at 50°. See video above (Fig.2) of a cooler night (Sept 29, 2021) at the same location the Snowies were singing on the 14th.
The songs of crickets and their relationship with temperatures is very interesting. Just last week it was warm enough for several Snowy Tree Crickets on the Keller Road tree line along the cornfield. See first recording. (Fig. 1.) And I have heard Snowy Tree Crickets singing there since then.
Below photos courtesy of the website “Songs of Insects”. They have photos, the songs and everything you want to know on over 300 singing insects of North America.
