What behavior is common in adult lesser house flies?

Lesser house flies exhibit behavior that includes hovering in midair within a room, which is characteristic of their movement patterns. This hovering allows them to observe their surroundings and potentially locate food sources or breeding sites. It is a common behavior that can be attributed to their flight patterns and feeding strategies, which are adapted for foraging.

Understanding this behavior is important in pest management since it highlights the fly's ability to navigate within indoor environments, making them more challenging to control. The other options describe behaviors that do not accurately reflect the lesser house fly's activities, as they are not known for immediately landing on food, traveling in large outdoor groups, or exclusively feeding at night.
