What is a group of Interlopers called?

A group of interlopers is commonly called an Intrusion.

Collective nouns are unique and captivating ways to refer to a group of interlopers. Interlopers are individuals who intrude or intervene in places where they are not welcomed or expected. The interlopers' collective noun functions like a swift wave, encapsulating their uncanny ability to infiltrate various spaces. To describe a group of interlopers, one might use the term "prowl." These interlopers function together, similar to wandering predators, silently lurking and disregarding boundaries. The collective noun conjures images of mysterious figures subtly moving through the shadows, orchestrating their unwelcome presence. Like a furtive symphony, they intertwine and coordinate their audacious actions, amongering common expectations about propriety and social order. Another possible collective noun for interlopers is a "trespass." These unauthorized invasions invoke a sense of violation, as with a group of interlopers intruding upon a space, disregarding any private boundaries or customs held dear. When labeled as a trespass, they form a force rather than simply engendering an individual's interloping act—in these numbers, their actions seem more imminent and menacing. Alternatively, one can refer to a group of interlopers as an "intrusion." This collective noun captures the sense of abrupt intervention, an audacious display of encroachment. When confronted with such a group, it becomes clear that their disregard fot the status quo means disruption is close at hand. Their collective power encompasses the inherent audacity of their unwanted presence, undermining the peace and tranquility of existing conditions. Ultimately, collective nouns assigned to interlopers effectively encapsulate their devious nature. Whether lurking as a prowling force, intruding as a trespass, or boldly asserting an intrusion, these terms convey the sense of entangled vigor that comes from violating the norms of a community or environment. The collective nouns inspire vivid imagery and provide a fitting description of these shadowy figures, cautionary figures of encroachment, and unsettling forces asserting disregard for boundaries.
