“Acarine” marks a sudden shift in the tone of the album: while the previous tracks are versed in boogie rock, Acarine is mainly psychedelic pop suddenly delving into house music on the instrumental outro, which displays synth elements that are fully realized in the next track.

“Acarine” refers to two things, the first being the the taxon Acari, a subclass of Arachnida found all over the world containing mites and ticks, and the second (which is referred to in the song) being the Acarine disease in bees caused by the mite Acarapis woodi, which belongs to this family.

The disease is caused by it crawling into the tracheae of bees through breathing holes or spiracles in their thorax or midsection.

Bees affected by this are unable to fly, have disjointed wings and distended abdomens, causing great suffering and eventually death.
