Määritelmä: arthropod sensory structures consisting of special sensilla called the scolopidia, which are mechano-transducers and respond mainly to stretch or flexion. In insects, they consist of bundles of internal sensilla, each of which has a cap cell, an enveloping cell and one or more sense cells.
