Cattus In ArcaJe suis fier d'annoncer que je viens de voir q'une des femelles de ma première colonie d'ispodes (porcellio scaber lava) avait le marsupium bien rempli ! Je vais avoir mes premiers petits !
Stefan F. Wirth#Isopod #Porcellio #hoffmannseggii is one of the largest known #terrestrial isopods. It is native to southern Spain, #Portugal, and #Morocco. Adults can reach a length of 4 centimeters.
It exhibits unusually strong #territorial #behavior and is also known for guarding its #offspring.
I am successfully #breeding this #species.

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.

FaroucheIt's #WoodlouseWednesday and I'm sick with a cold after visiting my family for the first time in years...
Found this 'albino' Porcellionides pruinosus in their compost bin, among many friends. The largest inhabitants of the compost were Porcellio laevis.
It's #WoodlouseWednesday ! Some captive-bred Porcellio sp. from Imi Ouaddar, Morocco.
I'm trading #isopods with another EU friend soon and need to decide on a locality name before I send them off. I need input.
How likely is it that foreign people will think my Porcellio scaber "Brittany" are from Britain, or named after Britney Spears, rather than from the Brittany region of France? Should I use "Breizh" or "Bretagne" for the locality instead? This is a polymorphic wildtype from the area, not a linebred morph project.
It's #WoodlouseWednesday ! Another Porcellio scaber from my locality bin.

It's #WoodlouseWednesday ! Let's take a look at these Porcellio incanus for a moment.
