Clip of a full color video rate imaging of a caterpillar on a strawberry leaf. Observation of a crawling movement of the caterpillar across a gap in the strawberry leaf. White scale bars correspond to 500 μm. A yellowish tint on the captured video appeared due to the spectral distribution of the used light source (a spectrum of the light source is shown in Additional file 1)
