These are the 5 species/varieties of isopod I found living under boards and stones in my back yard (NY state, USA) when the snow melted for a day last month. I'm looking forward to hunting around for more if spring ever arrives. Thanks very much to @Aquarimax for helping me confirm the IDs
An excellent chart! We need one of these... but will ALL the morphs and species! Your stuff should be in a book.
(Also, any tips for photography on white backgrounds? I'm looking to do something similar though I doubt it'll turn out as nice)
Thanks for the compliments! They are roughly to comparative scale, but only by eyeballing it. I didn't measure it out with precision. The technique is a field studio method that's very flexible and not that difficult for just about anyone to come up to speed on and get better at it.
