Not sure whether this is a suitable observation as there is no trace of life(insect) in these images. Would like to know if these are some kind of Ant trails(pheromone trails) and what causes the trails to become so prominently visible. There were many such lines throughout on the rocky-groud of the plateau. No ants/insects were seen. The trail lines ended at the pile of seed chaffs.

Something looks like a spider nest in the forest.
