h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I'm doing an experiment at college, I'd like to use a random sample of different species of Woodlouse to test an hypothesis.

My question is does anyone know from where I might be able to source the necessary different species?

Dig them out of a piece of wood?

http://en.wikipedia.org/wiki/List_of_woodlice_of_the_British_Isles List of cold facts without any decent writing which gives details of UK woodlouse species and where they can be found.

Had a new idea for a hypothesis which I'm going to try instead - which doesn't require using two different species.

What's your hypothesis?

I bet the finding will be

"mmmmm Crunchy!"

I'll volunteer!

Oh, sorry. You said 'invertebrates', not 'inebriates'...

Originally I wanted to test the preference for soil types according to different species and their relative distribution of habitats (certain species are clustered in the south where the soil is more chalk-based)

But just today I came across a word thigmokinesis - which is the tendency of invertebrates to slow down and stop when they touch something - the greater the surface area and the type of surface apparently correlates with their movement: this is used to explain why woodlice cluster together in crevices, it is further hypothesises that this is due to conserving water.

That's somethign I can test (and I wont have to do anythign fiddly like identify which species of woodlouse I'm looking at.)
