According to the formula, the ambient temperature for your cricket should
have been close to 55F. However, it could easily have been colder because if
the temperature is dropping quickly, there's a lag. The body temperature of
the cricket may be higher than the air temperature, especially right around
dusk when the temperature is changing quickly.
Not as interesting as Tiawan, but since things are quiet I will post
some quiet.
In the past here I have posted Spring Peeper frogs when they go flat
from the cold at 30F and Katydids changing their calls as they freeze
out in the 40's.
Here is a standard Cricket heard throughout the US. Many here know a
whole lot more about these little critters than I do. Like maybe
their formal name.
Between 46 and 49 degrees they get very quiet in their calls, ok
stridulations. I got a few chirps at a couple degrees colder but
then he was so quiet that the background is unpleasant to listen too
even recorded at 4 feet. Linked is when the chirps change and split
into two, just before quit time.
