Identification
Size 4.5 to 5 mm. Acidota cruentata can be distinguished from the very
similar Acidota crenata by the shape of the pronotum. In A. cruentata
the pronotum is wider than long, while in A. crenata it is longer than
wide. The habitus of the genus is very similar to other species of the
subfamily Omaliinae; jizz identification of Acidota also involves the
elongate overall shape with almost parallel sides of the abdomen and the
small head that is much narrower than the width of the pronotum.

Biology
A wintertime species; imagines appear in late autumn and can be found
until spring. They live in moist leaf litter. On warm winter days they
appear to be attracted to sun-heated sites (e.g. tree trunks, stones)
and then can also be found on house walls. The species is regarded to be
rare in Germany, but this might rather reflect the reduced collecting
activity of entomologists in the winter months.
