moth behaviour

[jhimmel at connix.com]

Hi LEPsers - 

I have come across a number of moth species, most often in the subfamily 
Plusiinae (Loopers) and some of the Zales, that rest with either a single tuftof 
scales, or several tufts erected from their upper thorax.  Does anyone know if 
this has something to do with pheromone release?  Incidentally, they tend to be 
very docile when in this position and may stay in the same place for days.

                tuft

Thanks in advance for any insight.
