I have done some night time collecting in the woods in Maryland. I had done
extensive daytime collecting in that area before & perhaps because of that,
I did not find any species at night that I hadn't already seen. I saw lots
slugs & Anguispira fergusoni crawling on trees, but I have seen them do
that also on rainy days during the day.

Going out into the woods at night was exciting, but it was also very easy
to get disoriented, because visibility was very limited & every tree looked
the same. Before I went back for a second night, I visited the area during
the day & laid out a path by tying a long yellow string along the trees.

I also got caught in a thunderstorm once at night in the woods. That was
scary.
