This tiny (2-4
mm), whitish woodlouse, is known from the Azores, the north Mediterranean and
Black Sea coasts. It inhabits the nest of several species of ants in the
genera Formica, Lasius, Linepithema and Messor. It was found outside of that region, in Hungary, within the nests of
Lasius neglectus. For a summary update of its distribution and biology

1.2. Platyarthrus hoffmannseggii Brandt,
This woodlouse is widely distributed in Europe. It has been detected in nests of
L. neglectus in Belgium (Dekoninck et al. 2007), showing that this
ant is able to host also local woodlouse species. See the distinct aspect of
the two Platyarthrus species in the following image.

One beetle was recovered in the nest of Lasius neglectus at
an outpost of the extensive Seva (Barcelona, Spain) supercolony. It feeds by
forcing regurgitation in returning laden workers. If attacked, the beetle
crouches down and is protected by its peculiar cuticular flanges.

populations in Barcelona province: Bellaterra (one female, 2.iv.2003; one
male, 16.vi.2004), Seva (one male, one female, 30.iv.2003), Begues (one

a look at those nervous, interesting crickets!

Cyphoderus albinus Nicolet, 1842 (Cyphoderidae)
This springtail has been recently found
in nests of L. neglectus in Belgium (Dekoninck et al. 2007). The
species is a common occurrence within nests of European ants.
