Anquake

Anquake is a term used to describe a phenomenon where a species of nocturnal insects, primarily the Anopheles mosquito, exhibits unusually synchronized and widespread activity. This activity typically occurs during periods of specific lunar phases, most commonly the new moon, and is believed to be triggered by subtle changes in ambient light levels. The insects emerge in large numbers from their daytime resting places, often from dense vegetation or water bodies, creating a noticeable increase in their population density and buzzing sounds. This synchronized emergence is thought to be an evolutionary adaptation for mating and dispersal.

While the term "anquake" is not a formal scientific classification, it is used colloquially by entomologists and residents in affected areas to describe the striking and often unnerving display of insect activity. The phenomenon is most frequently observed in tropical and subtropical regions where Anopheles mosquitoes are prevalent. The increased mosquito populations during an anquake can raise concerns about potential increases in vector-borne diseases, although the duration of the heightened activity is usually limited to a few nights. Research into the precise mechanisms and triggers of anquakes is ongoing, focusing on the interplay between lunar cycles, environmental factors, and the insects' biological rhythms.
