Silverfish Swarm

It's uncommon for silverfish to congregate in sufficient numbers to constitute a swarm, but forgotten libraries or similar out-of-the-way places might harbor a multitude of the voracious pests.

Silverfish

Source Pathfinder #169: Kindled Magic pg. 84
A common pest with a silvery carapace and an undulating, fishlike scuttle, the nocturnal silverfish infests homes and libraries throughout Golarion. These insects aren't typically dangerous, but their tendency to devour books and clothing often puts them at odds with larger creatures.

Sidebar - Treasure and Rewards Silverfish Molts

In an interesting twist to the pest's life cycle, some spellcasters incorporate giant silverfish moltings into their spellbooks and scrolls. These shed skins have the consistency of onionskin and are valuable due to the superstition that they contain residual magic from texts the silverfish consumed. Regardless of whether a silverfish molt has any intrinsic magical power, many tenured mages feel that proof of a book-devouring vermin's demise is worthy of a reward. Thus, such a trophy is guaranteed to fetch a tidy sum from the right buyer.
