V, S, M/DF (a square of red cloth)
1 round, concentration + 2 rounds, close
You summon a swarm of bats, rats, spiders (your choice), which attacks all other creatures within its area. (You may summon the swarm so that it shares the area of other creatures.) If no living creatures are within its area, the swarm attacks or pursues the nearest creature as best it can. The caster has no control over its target or direction of travel.
Effect: one swarm of bats, rats, or spiders

Although not cosmically aligned with the unsanctioned deity, Panopticon, the Eyes and Arms, the variant of the spell that summons Spiders is commonly used by Panopticon's followers due to its association with the deity's favoured animal.  
Bug Mask
On Goldday, Tailormoon, 1313, Fake-Yvette used a Bug Mask to summon swarms of Wasps inside the bodies of all of the nobility she had infected with the Shakes. The attack led to the deaths of Viziera Weaver Carterhold and Katiba Ursula Stargazer, although many of the other affected nobles were also badly hurt.   During the attack, Viziera Katharine Ironside disappeared from the Noble District to escape the Wasps, leading to a series of events that eventually led to her banishment on Copperday, Soldiermoon, 1313.
