Adult Picture-winged barklouse subadults tend to be larger but still developing wings. You can spot them in transition locations like branches or twigs, still keeping close to their food sources. Observing their movement and development within those microhabitats with the aid of a hand lens or binoculars could be successful.

They are often found on the barks of trees or shrubs, and can also be seen flying near lights at night. To find adult picture-winged barklouse, examine the trunk and branches of trees, especially during dusk when they might be more visible.
