[NHCOLL-L:3313] Re: Recrystallizing naphthalene on natural history

[Doug Yanega]

This phenomenon is very common in insect collections that use 
naphthalene fumigant, though it is peculiarly selective - only 
certain specimens will develop crystals, sitting millimeters away 
from specimens that are completely crystal-free. Generally, until and 
unless a particular specimen MUST be cleaned for some particular 
purpose, most curators just let such specimens stay as is.

Peace,
