Pyrrhocoridae contains four Australian genera. Cotton Stainers are so called as their squashed bodies would stain cotton red when they were processed with the bolls that they fed on. In Tasmania they are represented by the Harlequin bug (Dindymus versicolor), which is usually recognised for its bright colours and wandering around back-to-back mating. They are commonly found in gardens, usually nesting in large numbers around dead wood.
