Aradidae bear the appropriate common name, flat bugs, in reference to their (usually) extremely flattened body. With few exceptions, these often cryptic insects are of no economic importance. Common temperate genera include Aradus, Mezira, Neuroctenus, and Aneurus. Temperate species commonly live under the bark of dead trees (again, with a few exceptions), while many tropical species are found in leaflitter or on fallen twigs or branches.
