This short video shows woodants avoiding direct sunlight on their nest. Many ant-hills are positioned in a way that the sun is able to warm up the nest. A constant temperature inside the dome is necessary for the ant breed and a healthy offspring. The day this video was taken the temperature was only 18°C, wich should not be a problem for the ants. But the sun’s radiative flux was over 800 W/m2 and which seems far too much. Observing the behaviour of the woodants you will see them running into the light and turn around directly. Zooming out shows this pattern of running ants on the shaded side of the nest and into some holes in the dome that are probably used to get rid of humid air.
