What fundamental nocturnal activity of the adult Christmas beetles frequently results in them entering homes?
Answer
Congregating around artificial light sources
After spending their days feeding on foliage, the active adult Christmas beetles engage in distinct nocturnal behavior that often brings them into close proximity with human habitation. A fundamental part of their nighttime activity involves being strongly attracted to artificial light sources, both indoor and outdoor. This phototaxis causes them to congregate around lights, leading to the common scenario where they are found flying against windows or entering homes. While this behavior can be annoying to residents, it is a natural component of their lifecycle following daytime feeding.
