Just scoping out a tree for a trapout -- folks have serious allergies -- and I've noticed strange posturing around the two entrances.
There weren't that many there today but you can see how they were lined up, not seriously fanning but just sitting there in rows. (There were actual rings of rows yesterday.) It wasn't that hot so I don't thing they are trying to enhance the air-flow for cooling.
Does anyone have an idea about what's going on?
