Where then do they rest?  Is it possible they flitter up to the tree and then
veer off because of the squad of scientists lurking nearby?  Perhaps they like
to rest in the cool, steady shadow behind the scientist peering at the same
spot on the tree for however long it takes to determine there are no moths
there.
Or perhaps trees don't have to be peered at in person.  Perhaps the process
has been automated with a camera and flashing strobe (to save film).  Perhaps
the moths don't like disco.
Fourty years.  A career in tree peering.  I think someone should go tack a
moth to the tree just to give the new retiree some satisfaction.  (The moth
should have died of old age after a lengthy career of peering at the
scientists and wondering what the he** they are doing.)
