Hmmm .... I don't know if they jump, have to check next time I am inspecting. So far I've just seen them walking around, but I didn't try to touch them.
In the meantime, when you said " Springtails, another sapprophyte (like the pill bugs) " I thought gee, I would have called the pillbug a detritovore, I wonder if there's a difference, so I looked it up to try to educate myself.
I found this:
Saprophyte' (-phyte meaning 'plant') is a botanical term that is now considered obsolete. There are no real saprotrophic organisms that are embryophytes, and fungi and bacteria are no longer placed in the Plant Kingdom. Plants that were once considered saprophytes, such as non-photosynthetic orchids and monotropes, are now known to be parasites on fungi. These species are now termed myco-heterotrophs.http://en.wikipedia.org/wiki/Detritivore
Ã¢â‚¬Å“Detritivores are decomposers. According to the Ã¢â‚¬ËœrealÃ¢â‚¬â„¢ knowledge, decomposers consist of detritivores and saprophytes. Saprophytes are what we usually consider when talking about decomposers but technically speaking, that is not specific to them only.
Detritivores are animal that consume that detritus but unlike saprophytes, they cannot decompose cellulose (like most animals). They are forced to excrete anything they cannot digest.
Saprophytes, on the other hand, are basically microbes such as bacteria that digest detritus completely (including cellulose). They usually do this by extracellular digestion.
In the soil, both of these work hand in hand. After the detrivores excrete the waste materials, the saprophytes decompose them further. The detrivores have helped in breaking down most of the detritus into smaller pieces, increasing the surface area for the bacteria to act on.Ã¢â‚¬
