results of drying and degreasing methods

I appreciated the information from everyone on how they dry specimens in
humid weather and other problems. Some results and notes below.
1. Drying in the parked car seemed to work well. It is very fast (one
day). About a third of the polyphemus moth specimens got visible grease
on them, usually along the border between the fore and hind wings (the
overlap of the wings probably makes a tube for it to travel from the
abdomen); the rest did not.
NB - With styrofoam spreading boards you can easily wash the grease off
them; with wooden ones this would have been a mess.
2. Degreasing the abdomens in 2 successive soakings of VMP naptha worked
well, but I couldn't figure out a good way to label the abdomens to which
moth it went to.
3. Degreasing a whole spread specimen takes a LOT of naptha, and it seems
you must turn the specimen over and soak both sides. If you just soak it
on its back, the legs stick out of the naptha and remain covered with
grease. Soaking a single polyphemus on both sides requires two successive
baths of fresh naptha 5" wide and 1.5" deep (to accommodate the pin through
it). This is expensive and a pain.
NB - Collect smaller moths - it's cheaper.
4. I am told that specimens can still be degreased after glueing the
abdomen back on with Elmer's glue, although it will fall off and have to be
reglued. But I think I'm out of gumption!
