Spent silverfish, massed on black whippets at the end of the track cracked nut shells, lying inflated balloons, dying.
Steel mosquitos that tattoo poppies shot up cartridges by the school gate in new mown grass that stinks the street.
The poem is about drug use in the area I live. The silver fish are nitrous oxide canisters left discarded on the black streets - also known as whippets. Steel mosquitos are syringes.
