Northern nomad- marshland border

A group of nomad foragers in the swamplands realized that they've made a grave mistake when they ventured too deep into the borders between the swamp and the collosal forests
As one goes nearer into the towering jungles of the north, the landscapes would begin to change into something resembling no man's land, no large megafaunas that usually inhabit the prairies or swamps are to be seen anywhere, only creatures small enough to hide inside burrows or crevices. The plants that do grow resembles nothing like the normal vegetations the nomads usually see, instead they look more like gigantic versions of plants that grow in the dark forest floors. Because that's exactly what they are.

The nomads realized they have caught the attention of one of the insect giants from the forest, ironically a monstrous land-bound descendant of old world mosquitoes, though the females are flightless giants, the smaller males can be seen hovering over the trees far at the back.
