The two most common #woodlice in Central Europe in deadwood in #Berlin: #Porcellio #scaber and #Oniscus #asellus, #detritusfeeders. Both originate from Western Europe and appear as neozoa e.g. in America. Their #ecologicalrequirements differ: O. asellus tolerates #drought better. P. Zidar et al. (2003) found in choicetests that O. asellus properly #detects #foodqualities, which might be of #hygienic applied interest.

The #woodlouse #Oniscus #asellus (Oniscidae) is originally distributed in Western #Europe, but today one of the most common isopods in #CentralEurope, occuring e g. in dead wood or #leaflitter and is neozoon in North America. D. T. Bilton (2008), names two morphologically/ecologically different #subspecies, O. asellus asellus and O. asellus #occidentalis.

It's #WoodlouseWednesday ! I am so, so exhausted this week so very quickly: some orange Oniscus asellus individuals from the colony I started with isopods found in my previous dwelling's garden years ago.

It's #WoodlouseWednesday ! I went to look for Oniscus asellus occidentalis in the wild in February and found these stunning guys. I'm trying to capture them on pictures with the new camera but still learning.

It's #WoodlouseWednesday ! Here is a recent picture of local Oniscus asellus variety.
