I haven't quantified this, but my sense is that the vast majority of ww observations are of stationary moths on tree trunks. And several anecdotes suggest that a given moth will be on the same tree on successive days. Chances are, this is because the moths are nocturnal, and spend their days trying to look lichens on bark. What if an observer watched that stationary moth until after dark? It would probably be impossible to track. But what if the resting place was close to oviposition sites? Or the location of mating?
