Below is the abstract from the article containing this video:
Mating behavior often exhibits lateralization in animals. Highly confined environments, such as termite nests, may impose spatial constraints on mating behaviors, favoring directional biases. Here, we report that the rove beetle Trichopsenius japonicus, associated with the termite Reticulitermes speratus, consistently extends its genitalia leftward during mating. The layered nests of R. speratus, which consist of vertically narrow chambers, may contribute to this directional behavior. This study provides the first video-based documentation of a rove beetle’s mating behavior within termite nests.
