Heat-seeker

The heat-seeker is a very strange life-form, slightly resembling a furry butterfly. Travelling in swarms of hundreds, the heat-seeker has the ability to sense sources of warmth that include Humanoids and some kinds of equipment. Once they locate the source of warmth, the swarm moves lightly against it for several minutes to absorb the infrared emissions. After a few minutes, the insects fly off, having 'fed' on the passive heat-radiation without harming anyone or anything. The only danger is if the swarm got sucked into air intakes on equipment, in which case some damage might be done to the equipment, or if heat-seekers accidentally suffocated someone by blocking respiration through the nose and mouth.
