That is neat Zach. What is your method of marking?
there are various 'glow in the dark'/flourescent-enamel paints available. The right self tested colors of nail polish can also work. look for "NON TOXIC".
You can mark each desired individual with simple combinations of dots, shapes, numbers(often difficult to clearly mark, and often needs more marking paint than needed), and colors. I try to keep applications minimal, and ofcourse take extreme caution to keep clear of egs/joints/trichobothria/and the eye tubercles. When you get to your desired number of marked specimens, you can make a photo or drawn record-ID book.
Download to a plam pilot, or print it out, and ID individuals in the field in minutes. (You could even just draw the pattern in a field/locality notebook when recording minimal specimens).
I have found it to be more enjoyable to mark one in nearby survey spots
than to collect them (preserving them is debatable), i use similar methods in sampling theraphosids aswell. But this method also works great in sampling
areas for estimated population size/density/ and community structures.
