Soil temperatures were taken in the present study only when the turtle was in a form, hibernaculum, or den.
Young caterpillar with hibernaculum (h); caterpillar and chrysalis.
It seems that having migrated to a ledge, the racer promptly finds its hibernaculum and retires for the winter.
There is little movement during dormancy except for the deepening or horizontal extension of the hibernaculum.
This trend suggests that over periods of years a racer is likely to shift its range or its hibernaculum or both.
When the hibernaculum is finished the seam is perfectly smooth and the hole inside is lined with silk.
hibernaculum: a tent or sheath made out of a leaf or other material in which a larva hides or hibernates.
