How is the flight style of adult *E. sarcitrella* often described?
Answer
Weak fliers, exhibiting fluttery, erratic movements
Beyond static physical characteristics, the way the adult moth interacts with the air provides a useful secondary clue for identification. Adults of the White-shouldered House Moth are commonly characterized as weak fliers. When disturbed, their movement is not direct or strong, but rather described as fluttery and erratic. This suggests that the physical structure of the moth is optimized for short bursts or hops rather than sustained aerial navigation, often leading them to settle quickly nearby after being disturbed from a dark corner. This contrast in flight performance helps differentiate *E. sarcitrella* from more active, sustained flyers found indoors.
