Diapausing caterpillars

Two months have passed since the ground nesting caterpillars left their nests. Although the caterpillars leave the nest in a procession, they break into smaller processions and eventually split off individually or into smaller groups to find a suitable resting spot. These caterpillars can rest underground for approximately 4 months without feeding.

This caterpillar was found 4cm below ground. It will soon spin a cocoon to start its transformation from caterpillar to moth, known as pupation.
