Answer:
The poetic device used is Imagery.
Explanation:
“Death of a Naturalist" is a poem which was written by Seamus Heaney. Seamus Heaney is an Irish Nobel-Prize winning poet.

"The rotting flax “swelter[s]” in the sun every day; it releases “Bubbles” that burble up from the depths of the swamp. And bluebottle flies constantly buzz around it.
