caterpillar distance travelled
By Stevesw

Why would hundreds of caterpillars spend the last fews days travelling along a footpath(200/300metres),cross a road apparently into a field.I ask this question because today they appear to be going back. The behavior appears strange to a novice caterpillar watcher. Could any body shed any light on the reason why. ps colour black predominently, sorry should have taken a photo

The only thing I can think of is that they latched on to a new food source. When that ran out, instinct prompted them to return to their original food source, which may have recovered in the meantime from their predations.
