Woodlice in modified picture from Terrestrial Ecotoxicity Tests in New Zealand.
Woodlice are a common type of bug which shows a kinesis type of response to the humidity. They will increase in speed of movement in dry conditions. However, in humid conditions, their speed of movement decreases, and slows down. They will also have a tendency to turn more frequently, sometimes resulting in a constant circular pathway. This response causes them to make their habitat a humid region.
